Diameter of the wheel of the car = 80 cm
Radius (r) of the wheel of the car = 40 cm
Circumference of wheel
= 2πr = 2π (40) = 80π cm
Speed of car = 66 km/hour
Distance travelled by the car in 10 minutes
= 110000 × 10 = 1100000 cm
Let the number of revolutions of the wheel of the car be n. n × Distance travelled in 1 revolution (i.e., circumference) = Distance travelled in 10 minutes
Therefore, each wheel of the car will make 4375 revolutions.
