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 = 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
