Two trains each of length 50 m are approaching each other on parallel rails. Their velocities are 10 m/sec and 15 m/sec. They will cross each other in.

The correct option is C 10 secRelative velocity of the faster train with respect to the slower is 15−10=5m/s. The time taken for the faster train to travel 50m ist=505=10s which is our required answer.

Two trains each of length $50 m$ are approaching each other on parallel rails. Their velocities are $10 m / s e c$ and $15 m / s e c$ . They will cross each other in.

The correct option is C $10 sec$
Relative velocity of the faster train with respect to the slower is $15 - 10 = 5 m / s$ .
The time taken for the faster train to travel $50 m$ is
$t = \frac{50}{5} = 10 s$ which is our required answer.
