Question

A cyclist goes once round a circular track of diameter 126m in 5 min. Calculate its speed.

Answer 1

Hey.....!


For finding speed we need to find distance covered. So lets calculate distance which is circumference of circle.

Diameter = 126m
Radius = D/2
= 63m

Circumference= 2πr
= 2×22/7 × 63
= 396m

Now, Let's calculate his speed

Distance= 396m
Time = 5min = 300s

Speed = Distance/Time
= 396/300
= 1.32m/s


Here's our Answer...Speed = 1.32m/s
