Time is taken by train x to cover distance = 1 hour

Time is taken by train y to cover the distance = 1.5 hour

Speeds' Ratio of x & y = 3: 2

If x has to cover the entire journey (5 units) then the time is taken = 60 minutes

But to meet with y x has to cover only,

So the time taken by A to cover 3 units = 60/5 x 3 => 36

Meeting Time = 4 + 36 min => 4 : 36
