Two Trains 400m And 300m Long Run At The Speeds Of 50 Kmph And 40kmph Respectively In Opposite Directions On Parallel Tracks. The Time Taken To Cross Each Other?

Answer»

TRAINS are running in opposite Direction:

So need to FIND Length of two Trains = 300m + 400m = 700M

and Total SPEED = 40 Kmph + 50 Kmph (Opposite Direction)

= 90 Kmph

so speed (m/sec) = 90 * 5/18 m/sec = 25 m/sec

Formula Used: Time = Distance/Speed

Time = 700/ 25 sec

Time = 28 Sec.
