Distance between them 15 min after they meet each other is 90 km.
A train runs from A to B at 100km/hr. Without any stops and another one from B to A at 80km/hr.
We have to find the distance between the trains 15 minutes after they meet each other.
First, We should find relative speed of both trains.
Both are traveling opposite to each other, so the relative speed of trains would be sum of speed of trains.
i.e., relative speed of trains = (100 + 80) km/h = 180 km/h
Now the distance between them 15 min after they meet each other = relative speed × time taken by them after they meet
= 180 km/h × 15 min
= 180 km/h × 1/4 h
= 90 km
