Verified Answer
Two trains are each 50 m long moving parallel to each other at speeds ...
 As both the trains are moving in the opposite direction, the relative speed of each train with respect to each other be, v=10+15=25m/s
Here distance covered by each train = sum of their lengths =50+50=100m
∴ Required time=100/25​=4sec

Two trains are each 50 m long moving parallel to each other at speeds ...
Trains moving towards each other in opposite direction since, relative velocity Vrel=10+15=25. & total distance for crossing d= 50+50=100..... so, t= d/Vrel.=100/24 =4 sec
