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

minutes 20 seconds?


Distance covered in 40 seconds=200m
speed =200/40=5m/s
therefore,distance covered in 2 minutes 20 seconds or 140 seconds =5m/s × 140 sec
=750 m.
therefore,displacement at tye end of 140 seconds=0.
[displacement is zero because the athlete is moving on a circular track.he is coming back to its initial position.]
