Question

20. Two trains running in opposite directions
cross a man standing on the platform in
54s and 34s respectively and they cross
each other in 46 s. Find the ratio of their
speeds.​

Answer 1

Step-by-step explanation:

Let the speeds of the two trains be x m/sec and y m/sec .

Then, length of the first train = 27x metres

and length of the second train = 17y metres.

27x+17y/x+y=23

27x+17y=23x+23y

4x=6y

x/y=3/2

Hence The ratio of their speeds is 3:2
