Question

an athelete completes a round of a circular track of diameter 100m in 20seconds find his distance covered after 1m 10s​

Answer 1

Answer: 2198 m

Explanation:

Distance covered in 20 sec. = 2πr

i.e., 2πr = 2× 3.14× 100

= 628 m

In 20 sec. = 628 m is covered

Therefore,

In 1 min 10 sec (70 sec) distance

covered = (628/20) × 70

= 2198 m
