Two trains of length 125 m each are coming from opposite directions. If the speeds of 2 trains are 18 m/s and 22 m/s, then find the time in which 2 trains will cross each other.
Calculate the combined length of the two trains: 125 m + 125 m = 250 m
Calculate the relative speed of the two trains by adding the speed of the train: 22 m/s + 18 m/s = 40 m/s
Divide the combined length of the two trains by the relative speed to find the time it takes for them to cross each other: 250 m / 40 m/s = 25/4 seconds
So it will take the two trains 25/4 seconds to cross each other.
