Question

A cyclist moving on a circular track of radius 100 m completes one revolution in 4 minutes . What is his average speed​

Answer 1

Answer:

Explanation:

Average speed= total distance travelled/total time taken

here, total distance travelled=circumcenter of the path=2πr

                                         =2*(22/7)*100 metre=628.57m

total time taken=4 min=4*60 sec=240 sec

average speed=total distance/total time=628.57/240=2.62m/s

Answer 2

Answer:

2.62m/s

Explanation:

Radius=100m

circumference=2πr

                       =2*22/7*100

                      =628.6m

time=4min =240sec

Average speed = Total distance travelled/total time

                          = 628.6/240

                          = 2.62m/s
