A car moves with a constant speed through 150 m in 5 s.What is its speed?
A.
30 m/s
B.
0.033 m/s
C.
750 m/s
D.
0 m/s
Correct Answer A. 30 m/s
Explanation The car moves a distance of 150 m in a time of 5 s. To find the speed, we divide the distance by the time, which gives us 150 m / 5 s = 30 m/s. Therefore, the speed of the car is 30 m/s.

D.
63.89 km/h
Correct Answer C. 60 km/h
Explanation The average speed of a journey is calculated by dividing the total distance traveled by the total time taken. In this case, the car traveled a total distance of 1200 km in a total time of 20 hours. Therefore, the average speed of the journey would be 1200 km divided by 20 hours, which equals 60 km/h.

An aeroplane moves with a constant speed of 120 m/s.Find the distance travelled in 1 minute?
A.
120 m
B.
2 m
C.
7200 m
D.
0.5 m
Correct Answer C. 7200 m
Explanation The distance travelled by the airplane can be calculated by multiplying its speed by the time it takes to travel. In this case, the speed is given as 120 m/s and the time is 1 minute. Since 1 minute is equal to 60 seconds, the distance travelled would be 120 m/s * 60 s = 7200 m.
