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?



72km/h means 1.2km/minute

1). 810 KM / 1.2 KM = 675Minutes to cover 810 KM

This will reach next day 10:15AM

2). 810KM / 1.05 KM = 771.42 Minutes to cover 810 KM

This will reach next day 11:51AM
