Question

a cyclist completes 8 revolution of a circular track of radius 98 M with a uniform speed in 402 minutes calculate the speed

Answer 1

Radius of the circle=98m
Circumference or distance=
$2\pi \ r$
Revolutions=8
Total distance travelled=8x2x22/7 x 98
=16x22x14
=4928m
Time 402 min=402x60=24120sec
Speed=Distance/Time
=4928/24120
=0.17m/s
