Question

114) The velocities of car, a bike and a train are in the ratio 5:3:8. If a person travels equal distances by a car, a bike and a train, then what would be the ratio of the respective times taken to cover that distance? A) 24:40:25 B) 24:40:05 C) 24:20:15 D) 24:40:15​

Answer 1

Answer:

Let the speed of two trains be 7x and 8x km/hr.

Then, 8x={400}=100

4

⇒x={100}=12.5

8

∴ Speed of first train = (7 x 12.5) km/hr = 87.5 km/hr.
