Question

A Cyclist goes once round a circular track of diameter 105
meters in 5 min calculate his speed

Manu · Accepted Answer

If a cyclist takes t seconds to go around the circular path of radius r , then speed  Is given by:  Speed = 2πr/tHere  t = 5 min = 5*60 = 300 secdiameter = 105 mradius = 105/2 = 52
5 mSpeed = (2 * 22/7 * 52
5) / 300Speed  =1 1 m/s
