the rim of the wheels of a truck and van are 90cm and 60cm long respectively what is the least distance in which both make an exact number of turn

ᴀɴsᴡᴇʀ →

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 =

$\longmapsto\tt{\dfrac{7}{4400}=560}(352000) x$
