Question

An athlete completes one round of a circular track of diame
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:

diameter=200,thus radius = 200/2=100m

and time=40sec.

Explanation:

so.. distance=circumference of circle

2πr= 2*22/7*100

=2*3.14*100

=2*314

=628. so this is distance.

displacement=0

because his initial and final position that same.
