Question

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

Answer 1

Explanation:

Given radius = 100m

circumference = 2*3.14*100 = 628 m

He covered 628m in 40 secs

628 meters----->40 secs

x meters----->140 secs

x is distance travelled in 2mins 20secs

x = (140/40)*628 = 2198m is the distance travelled

Dispalcement will be 2meters because it is 2meters away from the starting point

This is ur answer. Hope it helps u
