Question

10. Train A, twice the length of train B, travels at 60 km/h while train B travels at 96 km/h. One train
passes the
other in 24 seconds when moving in the same direction. Find the lengths of the trains.​

Answer 1

Answer: I hope this will help you.

Step-by-step explanation:      When two train passes a moving object (having some length) in the same direction.

Let length of faster train be l meters and length of slower train be m meters

Speed of faster train be x km/hr and speed of slower train be y km/hr

Relative speed = (x – y) km/hr

Then, time taken by the faster train to pass the slower train = (l + m) meters/(x – y) km/hr

Note: Change km/hr to m/sec

Now we will learn to calculate when two trains running on parallel tracks (having some length) in the same direction.
