Two trains of length 55 metres and 65 metres travel in opposite directions with speed 70 km/hour and 50 km/hour respectively.
Find the time taken for them to completely cross one another.

The relative speed between the two trains: 70 + 50 = 120 km/hr
Change 120 km/hr to meters/sec
= 33 meters per sec

Find the no. of seconds to travel 55 + 65 = 120 meters
= 3.6 seconds
