Two trains start from the same station at 11p.m in opposite direction at speeds of 72km/h and 63km/h. at what time they will be 810 km apart?

Answers (1)

As trains move in the opposite direction, so the relative speeds of trains = 72 + 63 = 135 km/h

Distance =  810 km

Time = Distance/Speed = 810/135 = 6 hours

Hence at 5 a.m. they will be 810 km apart.
