Question

There is a town called metron, where wheels of the front and rear of vehicles are of different size. The measurement unit followed in the town is the metre. The circumference of the front wheel of the car is 133 metres and that of rear wheels is 190 metres. So what is the distance travelled by the cart in metres when the front wheel has done nine more revolutions than the rear wheel?

Answer 1

Answer:

3990 m

Step-by-step explanation:

There is a town called metron, where wheels of the front and rear of vehicles are of different size. The measurement unit followed in the town is the metre. The circumference of the front wheel of the car is 133 metres and that of rear wheels is 190 metres. So what is the distance travelled by the cart in metres when the front wheel has done nine more revolutions than the rear wheel?

Let say Rear Wheels revolved for  n times

Front Wheel Revolved = n + 9 time

Real Wheel covered distance = 190n

Front Wheel Covered Distance = 133(n + 9)

190n = 133(n + 9)

=> 57n = 133* 9

=> n = 21

Ditance Travelled = 190 * 21 = 3990 m
