A cyclist moving on a circular track of radius 140 m completes one revolution in 2 min. What is the average speed of the cyclist?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 440 m/min.
The radius of the circular path = 140 meters
Time taken by a cyclist to complete one round = 2 minutes
Total distance covered in one revolution = 2πr
= 2 × 22/7 × 140 = 880 m
Average speed = Total distance/total time
Average Speed = 880/2 = 440 m/min
