Answer:
The number of revolution is 4375.
Step-by-step explanation:
The given diamter of the wheel is 80cm
Therefore, radius = 40cm.
Thus the circumference of the wheel = 40 * 2* 22/7= 80*22/7 = 1760/7
The total time taken = 10mins = 1/6hr
The speed of the car = 66km/hr
Thus, total distance covered by the wheel = speed * time
= 66 * 1/6 = 11km = 1100000cm
The total number of revolutions = total distance covered / distance in 1 revolution.
Therefore, number of revolutions =1100000cm / 1760/7
This results to 4375 revolutions.
