gyan has a car whose wheel are 60 com diameter how many complete revolution does each wheel make in 15 minutes when the car is ravelling at a speed of 60km/hr

  • 3

d = 60cm
r = 30cm
Circumference = 2πr = 2*22/7*30 = 1320/7 cm
Speed of car = 60km / h
Time = 15 minutes = 0.25h

So, Distance = 60 * 0.25 = 15 km = 15,00,000 cm
No. of revolutions = 15,00,000 / (1320/7)

= 7954.54 (7955 revolutions in 15 minutes)
