An express train takes 1 hour less than a passenger train to travel 132 km between stations A and B (without taking into consideration the time they stop at intermediate stations). if the average speed of the express train is 11 km/hour than that of the passenger train, find the average speed of the two trains????

Let the average speed of passenger train be x km/h.
Average speed of express train = (x + 11) km/h
It is given that the time taken by the express train to cover 132 km is 1 hour less than the passenger train to cover the same distance.

Speed cannot be negative.
Therefore, the speed of the passenger train will be 33 km/h and thus, the speed of the express train will be 33 + 11 = 44 km/h.
