Question

The diameter of the wheel of a bus is 50cm if the speed of the bus is 33km/hr then the number of complete revolution it will make in 1 minute is ​

Answer 1

Answer:

Speed of the bus = 66 km/hr

Distance covered by the wheel in one minute =

60

66×1000×100

=110000 cm

Circumference of the wheel = 2×

7

22

×70=440 cm

Therefore, distance covered by the wheel in one revolution = 440 cm

Hence, number of revolutions in one minute =

440

110000

=250
