Here in this page we try to put all types of shortcut tricks on Train running same direction. But we may miss few of them. If you know anything else rather than this please do share with us. Your little help will help others.

 

 


Note: If direction is given in the same direction then we subtract both speeds.


Example #1
A train of 250 meter long is running at a speed of 65 km/hr. A man running at a speed of 5 km/hr, towards the same direction the train is moving. Find the time taken by the train to pass the man.

  1. 12 Seconds
  2. 15 Seconds
  3. 19 Seconds
  4. 23 Seconds

Answer: Option (B)
How to Solve
If direction is given in the same direction then we subtract it.
( 65 – 5 )
= 60 km/hr.

Now, converting it into m/sec.
60 x 5 / 18
= 50 / 3 m/sec.

The train covers total 250 meter.
So, to cover the distance the train needs,
250 x 3 / 50
= 15 sec.

Example #2
Two super fast train, 180 meters and 180 meters in length, are running in the same direction. The first train at the speed of 58 km/hr and the second one at the speed of 50 km/hr. What time will they be cross each other?

  1. 140 Seconds
  2. 148 Seconds
  3. 156 Seconds
  4. 162 Seconds

Answer: Option (D)
How to Solve
Two fast trains are running is same direction and their relative speed is,
58 – 50
= 8 km/hr.

Now, converting km/hr to m/sec.
8 x 5 / 18
= 20 / 9 m/sec.

So, the total length of both the train is,
( 180 + 180 )
= 360 meters.

So, the required time is,
Total length / Relative speed
= ( 180 + 180 ) x 9 / 20
= 360 x 9 / 20
= 162 sec.
