Correct Answer
A. 18Explanation
The highest common factor (HCF) is the largest number that divides all the given numbers without leaving any remainder. To find the HCF of 54, 288, and 360, we can start by finding the factors of the smallest number, which is 54. The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54. We then check if these factors divide the other two numbers evenly. Among these factors, 18 is the largest number that divides 288 and 360 without leaving any remainder.

A cyclist covers a distance of 750 meter in 2 minutes 30 seconds. What is the speed in km/hr of cyclist
- A.
24 km/hr
- B.
18 km/hr
- C.
30 km/jr
- D.
22 km/hr
Correct Answer
B. 18 km/hrExplanation
The cyclist covers a distance of 750 meters in 2 minutes and 30 seconds, which is equivalent to 2.5 minutes. To find the speed in km/hr, we need to convert the distance from meters to kilometers and the time from minutes to hours.
750 meters is equal to 0.75 kilometers (since 1 kilometer is equal to 1000 meters).
2.5 minutes is equal to 0.0417 hours (since 1 hour is equal to 60 minutes).
Dividing the distance (0.75 km) by the time (0.0417 hr) gives us a speed of approximately 18 km/hr.Rate this question:
