Two trains running with a speed of 84 km per hour and 48 km per hour respectively, starting at the same time, run in opposite directions
The relative speed of the two trains is the sum of their individual speeds, as they are moving in opposite directions.
Relative speed = Speed of Train 1 + Speed of Train 2
Relative speed = 84 km/h + 48 km/h
Relative speed = 132 km/h
Time = Distance / Speed
The distance they need to cover is the sum of the distances traveled by the two trains to meet each other, which is the total distance between the two stations, i.e., 924 km.
Time = 924 km / 132 km/h
Time = 7 hours
So, the two trains will cross each other in 7 hours after they start from stations P and Q.
