The diameter of a wheel of a car is 98 cm. How many revolutions will it make to travel 6160 meters. |
|
Answer» In one revolution of the wheel, the car travels a distance equal to the circumference of the wheel. Given diameter of the wheel of a car = 98 cm Circumference of the wheel of the car = π d = 227 x 98 = 308 cm The distance travelled by the car in one revolution = 308 cm Total distance travelled by the car = 6160 m = 616000 cm Therefore number of revolution = total distance travelled by the car/ distance travelled by the car in one hour Number of revolution = 616000/308 = 2000 |
