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.
