Question

10
The speed of two motor cyclist A and B are in the ratio 11:12
respectively. The motorcyclist travels 4.5 km less than the
motorcyclist B in the same duration What was the distance
travelled by motorcyclist B?​

Answer 1

Let the speed of the motor cyclist A be 11x Km/h

Let the speed of the motor cyclist B be 12x Km/h

Let the time duration be T hrs

Distance Travelled by A = 11Tx km

Distance Travelled by B = 12Tx km

11 Tx + 4.5 = 12Tx

12 Tx – 11 Tx = 4.5

Tx = 4.5

Now distance travelled by

B = 12Tx

B = 12 × 4.5

B = 54 Km

Hope the solution is clear to you!!
