Question

An athlete completes one on round of circular track of diameter 200m in 40 seconds will be the distance covered and the displacement at the end of 2 minutes 20 seconds

Answer 1

Answer:

, the answer is explained above

Answer 2

Given , r=100m

D=200m

T= 40 sec

Asked in 2 min 20 sec

First convert 2min into sec

2min 20 sec= 120+20

= 140seconds

Then given one round is covered in 40 seconds

40seconds - 1round

140seconds- - x

Then

40x=140

X=140÷40

X=3.5rounds

Given 1 round 200 m

Then 3.5 rounds

3.5×200= 700m
