I hope this is helpful to you

Answer 2

The speed of the cyclist is 1.57 m/sec.

Given,

Time taken by the cyclist to complete one round of the track = 20 minutes

The radius of the circular track = 20 minutes

To Find,

The speed of the cyclist.

Solution,

The formula for calculating the speed of an object is

Speed = Distance/Time

Time = 20 minutes = 20*60 =1200 seconds

The distance traveled by the cyclist will be equal to the circumference of the circle

So,

Distance = 2πr = 2*22/7*300 = 1885.7 m

Now,

Speed = 1885.7/1200 = 1.57 m/sec

Hence, the speed of the cyclist is 1.57 m/sec.
