Answer:

mam this the answer.

Step-by-step explanation:

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 = 2x22/7x70=440

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

Hence, number of revolutions in one minute =

440/110000=250
