Solution:
⇨ Given
⇨ t = 10 minutes = 10 x 60 = 600 seconds
⇨ v = 66 km/h
⇨ v = 66 x 1000/3600 m/s
⇨ v = 660/36 m/s
⇨ v = 110/6 m/s
⇨ v = 55/3 m/s
⇨ Distance covered by the car in 10 minutes
⇨ d = vt
⇨ d = 55/3 m/s x 600 sec
⇨ d = 11000 m
⇨ d = 1100000 cm
⇨ Radius of Wheels, r = 80/2 = 40 cm
⇨ Distance covered by the wheels in 1 revolution
= 2πr
= 2 x 22/7 x 40
= 44 x 40 / 7
= 1760/7
= 251.428 cm
⇨ Number of complete revolution each wheel make
= 1100000/251.428
= 4375.0099
