# Train Passes a Moving Object in the Opposite Direction

When train passes a moving object in the opposite direction

Let length of train = l meters and speed of train = x km/hr

Speed of the object = y km/hr and relative speed = (x + y) km/hr

Then, time taken by the train to pass the moving object = l meters/(x + y) km/hr

Now we will learn to calculate when train passes a moving object in the opposite direction.

Solved example:

A train 165 m long is running at the speed of 60 km/hr. In what time will it pass a man who is running at the speed of 6 km/hr in the opposite direction in which the train is moving?

Solution:

Man moving in the opposite direction in which the train is moving.

Speed of train relative to the man = (60 + 6) km/hr

= 66 km/hr

= 66 × 5/18 m/sec

= 55/3 m/sec

Time taken by the train to cross a man = length of train/speed of train relative to man

= 165 m/(55/3) m/sec

= (165 × 3/55) sec

= 9 sec
