Question

A cyclist goes around a circular track once every 1 minute If the radius of the circular track is 70 meters calculate his speed.(Given n=22/7)​

Answer 1

Explanation:

Here, diameter = 105m , radius (r) = 105 / 2

Time taken t = 5 × 60 = 300s

Speed , V = 2πr / t = 2 × 22 / 7 × 105 / 2 × 300 = 1.10 m/s .
