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:

2min 20sec=140sec

therefr distance, =700mt

displacement =20mt

Answer 2

Answer:

(110/7)*140m=2200m

Explanation:

ifwe find the circumference of the circle, It will be 2*22/7*100=4400/7

then ,we find the distance covered in one second = 4400/7*40=110/7m

then we find the total distance covered in 140s That is 2min 20 s=(110/7)*140m=2200m
