Answer:
After 3 hours the trains will cross each other.
Step-by-step explanation:
Let's assume that the trains will cross each other x hours after they started.
According to the problem:
In x hours, the first train covers 50x km
In same duration, the second train covers 65x km
Therefore, 50x + 65x = 345
=> 115x = 345
∴ x = 3
∴ After 3 hours the trains will cross each other.
