Question

An athlete completes one round of a circular track of diameter 200 m in 40 s. What will be the distance covered and the displacement at the end of 2 minutes 20 s?​

Answer 1

Answer:

speed = 2×3.14× 100 /40

= 15.7 m/s

distance= 15.7 × 140 = 2198 m

and displacement = 2198- 1884 = 314 m
