Question

An athelet complete one round of a circular track of diameter 200m in 40s. find the distance and displacement at the end of 3min 20 sec

Answer 1

Answer:

distance=1000 & displacement =0

Explanation:

An athlete completes one round that is 200m in 40s.

3min 20sec= 3× 60s + 20s = 200s.

let us see how many 40s are there in 200s .

200s ÷ 40s =5.

so in 200s athlete can cover 5rounds .

so from the first statement ,athlete cover 5×200m=1000m
