Question

An athlete completes one round of a circular track of diameter of 400m in 80 seconds. What will be the distance covered at the end of 2 minutes & 20 seconds?

Answer 1

Answer:

So distance covered in 2 minutes & 20 seconds

= 2,199.4 m

Step-by-step explanation:

Distance covered in 80 seconds

= circumference = pi D

= 3.142 × 400 m

= 1,256.8 m

So distance covered in 2 minutes & 20 seconds

= 1,256.8 × 140 ÷ 80

= 2,199.4 m
