Question

An athlete completes one round of a circular track of diameter 200m in 40s .what will be the distance covered and the displace ment at the end of 2m in 20s

Answer 1

Answer:

200m

Step-by-step explanation:

Radius 100m in 40s

perimeter is 2πr which is equal to 4400/7 m

in 2min 20s = 140s

3 and a half round will be completed...

since we have to find displacement

displacement is the diameter = 200 m
