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:

40 second = 200m = diameter

Radius = 100 m

s = d/t

Distance covered = 140s/40m

.... = 3.5 round

Circumference = 3.5×2πr

3.5×2×22/7×7

... 154 m
