Question

A cyclist goes around a circular track once every 2 min if the radius of the circular track is 105m. Calculate his speed.

Answer 1

Answer:

5.5 m/sec is the correct answer

Explanation:

Circumference of circle=660

Time=120 sec

Answer 2

Answer:

distance to be covered in each round is 2πr

=2*22/7*105

=44*15

=660m

time taken=2min=120sec

speed=distance/time

=660m/120s

=5.5m/s
