Question

Two trains running in opposite directions cross a signal pole in 54 seconds and 34 seconds
respectively. The trains take 46 seconds to cross each other. What is the ratio of their speeds?
1:3
O 3:4
O 3:2
O None of these​

Answer 1

Answer:

3 : 2

Step-by-step explanation:

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

Then, length of the first train = 54x metres,

and length of the second train = 34y metres.

54x + 34y / x + y = 46

54x + 34y = 46x + 46y

8x = 12y

x / y = 3 / 2
