Question

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

Answer 1

2 mins 20 sec= 140 sec

140= 40×3+20

distance= 3 and a half round,ie,

2πr=(2×22/7×100)×3.5

displacement= 200 m
