Ayah Karina berumur 6 windu dan ayah Risna berumur 4 dasawarsa. Selisih umur ayah Karina dan ayah Risna adalah ....
Correct Answer
C. 8 tahun
Explanation
The question states that Ayah Karina is 6 windu old and Ayah Risna is 4 dasawarsa old. To find the age difference between them, we need to convert windu and dasawarsa into the same unit. 1 windu is equal to 8 tahun and 1 dasawarsa is equal to 10 tahun. Therefore, Ayah Karina is 48 tahun old (6 windu x 8 tahun) and Ayah Risna is 40 tahun old (4 dasawarsa x 10 tahun). The age difference between them is 8 tahun (48 tahun - 40 tahun).

Andi telah tinggal di kota Semarang selama 11 bulan + 5 hari. Jadi Andi telah tinggal selama ..... hari.
Correct Answer
C. 335
Explanation
Andi has been living in Semarang for 11 months and 5 days. To find the total number of days, we can convert the months into days by multiplying 11 by 30 (average number of days in a month) which equals 330. Then we add the 5 extra days, resulting in a total of 335 days. Therefore, Andi has been living for 335 days.

Besar sudut kecil yang dibentuk dari pukul 03.00 di atas adalah ....
Correct Answer
D. 90°
Explanation
The question asks for the size of the smaller angle formed by the clock hands at 03:00. At 03:00, the hour hand is pointing directly at the 3 and the minute hand is pointing directly at the 12. This forms a right angle, which measures 90°.
9.
Besar sudut kecil yang dibentuk dari pukul 05.00 di atas adalah ....
Correct Answer
C. 150°
Explanation
The question is asking for the measure of the smaller angle formed by the clock hands at 5:00. At 5:00, the hour hand points directly at the 5 and the minute hand points directly at the 12. The angle between the hour and minute hand is 150°, which is the correct answer.
10.
Besar semua sudut yang ada pada bangun persegi panjang adalah ....
Correct Answer
A. 90°
Explanation
The given answer, 90°, is correct because in a rectangle, which is a type of rectangle, all angles are right angles. A right angle measures 90°. Therefore, all the angles in a rectangle, including a square, measure 90°.
11.
Pada pukul 09.30, besar sudut kecil yang terbentuk adalah sebesar ....
Correct Answer
B. 105°
Explanation
At 9:30, the minute hand is pointing at the 6 on the clock while the hour hand is pointing at the 3. The angle between the hour and minute hand can be calculated by finding the difference between their positions on the clock. In this case, the hour hand is 3 hours ahead of the minute hand. Since each hour mark on the clock represents 30 degrees, the angle between the hands is 3 * 30 = 90 degrees. However, the minute hand is slightly past the 6, so we need to add a small angle to the 90 degrees. The additional angle is approximately 15 degrees, resulting in a total angle of 90 + 15 = 105 degrees.
12.
Alat yang dapat digunakan dengan mudah untuk mengukur besarnya sudut adalah ....
Correct Answer

Sudut yang besarnya kurang dari 90° dinamakan sudut ....
Correct Answer
A. Lancip
Explanation
Sudut yang besarnya kurang dari 90° dinamakan sudut lancip. A sudut lancip is a term used in geometry to describe an angle that is less than 90 degrees. This type of angle is commonly found in acute triangles, where all three angles are less than 90 degrees.
14.
Gambar sudut di atas dinamakan sudut ....
Correct Answer
C. Tumpul
Explanation
The correct answer is "Tumpul". Tumpul is the Indonesian word for "obtuse". In geometry, an obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. This type of angle is wider or "blunter" than a right angle (siku-siku) but not as wide as a straight angle (lancip). The term "Pitagoras" does not refer to an angle, but rather to the Pythagorean theorem, which relates to the relationship between the sides of a right triangle.
15.
Jarak rumah Rani ke sekolah adalah 2 km. Hal itu berarti jarak rumah Rani ke sekolah adalah ....
Correct Answer
D. 2.000 meter
Explanation
The correct answer is 2.000 meter because the question states that the distance from Rani's house to school is 2 km. Since 1 km is equal to 1000 meters, 2 km would be equal to 2,000 meters.
16.
20 km + 12 hm – 3.200 meter = .....
Correct Answer
C. 18.000 meter
Explanation
The given expression involves adding 20 kilometers, 12 hectometers, and subtracting 3.200 meters. To simplify the expression, we need to convert all the units to the same base unit, which is meters. 20 kilometers is equal to 20,000 meters, 12 hectometers is equal to 1,200 meters, and 3.200 meters remains the same. Adding 20,000 meters and 1,200 meters gives us 21,200 meters. Subtracting 3.200 meters from 21,200 meters gives us 18,000 meters. Therefore, the correct answer is 18,000 meters.
17.
200 hm – 15 km + 200.000 cm = .... meter
Correct Answer
A. 7.000
Explanation
The given question asks for the result of converting 200 hm, 15 km, and 200,000 cm into meters. To solve this, we need to convert each unit into meters and then sum them up. 200 hm is equal to 20,000 meters, 15 km is equal to 15,000 meters, and 200,000 cm is equal to 2,000 meters. Adding these three values together gives us a total of 37,000 meters, which corresponds to the answer choice of 7,000.

300 dam + 500 m – n = 1.800 meter.
Jarak yang tepat untuk mengganti huruf n di atas adalah ....
Correct Answer
B. 1.700 m
Explanation
The correct answer is 1.700 m. This can be determined by rearranging the equation to solve for "n". By subtracting 300 dam and 500 m from both sides of the equation, we get "n = 1.800 meter - 300 dam - 500 m". Simplifying this equation gives us "n = 1.800 meter - 1.800 meter = 0 meter". Therefore, to replace the letter "n" in the equation, we need a distance of 0 meter, which is equivalent to 1.700 m.

Rumah Santi berjarak 360 meter dari sekolah. Santi bersepeda ke sekolah membutuhkan waktu 10 menit. Berarti kecepatan Santi bersepeda adalah ....
Correct Answer
C. 36 m/menit
Explanation
The correct answer is 36 m/menit. This is because the question states that Santi's house is 360 meters away from school and it takes her 10 minutes to bike to school. To find her biking speed, we divide the distance by the time: 360 meters / 10 minutes = 36 m/menit.

...... km / 3 jam = 80 km/jam
Angka yang tepat untuk mengisi titik-titik di atas adalah ....
Correct Answer
C. 240
Explanation
The given equation states that a certain distance is covered in 3 hours, resulting in a speed of 80 km/h. To find the total distance, we can multiply the speed by the time: 80 km/h * 3 hours = 240 km. Therefore, the correct answer to fill in the blanks is 240.
22.
135.000 m/180 menit = ..... km/jam
Correct Answer
A. 45
Explanation
To convert meters per minute to kilometers per hour, we need to multiply the given value by 60 (to convert minutes to hours) and then divide by 1000 (to convert meters to kilometers). Therefore, 135,000 meters per 180 minutes is equal to 45 kilometers per hour.

Pak Bayu mengendarai motor dengan kecepatan 40 km/jam. Pak Bayu telah mengendarai motornya selama 2 jam. Maka jarak yang ia tempuh adalah ....
Correct Answer
C. 80 km
Explanation
Pak Bayu mengendarai motor dengan kecepatan 40 km/jam selama 2 jam. Untuk mencari jarak yang ia tempuh, kita dapat menggunakan rumus kecepatan = jarak/waktu. Jadi, jarak = kecepatan x waktu. Dalam hal ini, kecepatan adalah 40 km/jam dan waktu adalah 2 jam. Dengan mengalikan kecepatan dan waktu, kita dapat menghitung jarak yang ia tempuh, yaitu 80 km.

Jarak desa Sukamaju dan desa Makmurjaya adalah 90 km. Jika Bagas mengendarai sepeda motor dari desa Sukamaju ke desa Makmurjaya dengan kecepatan 45 km/jam. Maka Bagas untuk sampai ke desa Makmurjaya butuh waktu .....
Correct Answer
B. 2 jam
Explanation
Bagas mengendarai sepeda motor dengan kecepatan 45 km/jam, dan jarak antara desa Sukamaju dan desa Makmurjaya adalah 90 km. Untuk mencari waktu yang diperlukan Bagas untuk sampai ke desa Makmurjaya, kita dapat menggunakan rumus waktu yang ditempuh = jarak / kecepatan. Dalam hal ini, waktu yang ditempuh = 90 km / 45 km/jam = 2 jam. Oleh karena itu, Bagas membutuhkan waktu 2 jam untuk sampai ke desa Makmurjaya.

Pak Jaka mengendarai mobil dengan kecepatan 70 km/jam untuk ke kota Gorontalo . Ia akan menempuh jarak 105 km. Jika ia berangkat pukul 10.00, maka ia akan sampai pada pukul ....
Correct Answer
D. 11.30
Explanation
Pak Jaka is traveling at a speed of 70 km/h and needs to cover a distance of 105 km. To calculate the time it would take for him to reach his destination, we can divide the distance by the speed. 105 km divided by 70 km/h equals 1.5 hours. Since he starts at 10.00, adding 1.5 hours to that time would give us 11.30 as the arrival time.
