hiGiven diameter of front wheel = 80 cm
radius of front wheel = 40 cm
circumference of circle (front wheel) = 2πr
= 2 x (22/7) x 40 = 1760/7 cm
Distance covered by the front wheel in 1400 revolutions = 1400 x (1760/7) = 352000 cm
Given diameter of rear wheel = 2 m = 200 cm
radius of rear wheel = 100 cm
circumference of circle (rear wheel) = 2πr
= 2 x (22/7) x 100 = 4400/7 cm
But distance covered by the rear wheel = 352000
Number of revolutions made by rear wheel = (352000) x (7/4400) = 560
