An express train takes I hr less than the passenger train to travel 132km between masur and banglor. If avg speed of express train is 11 km/hr more than that of passenger train. Find the avg speed of express train.

A train travels 480km at a uniform speed. If the speed had been 10km/hr more, it would have taken 4 hours less for the same journey, find the speed of the train?

a train travels a distance of 300km at constant speed. If the speed of the train is increased by 5km per hour the journey would have taken 2 hours less. Find the original speed of the train.

a goods train leaves a station at 5pm, follow by an express train which leaves at 7 pm and travels 20km/hr faster than the goods train. The express train arrives at a station, 1040 km away, 36 minutes before the good train. Assuming that the speed of both the trains remain constant between the two stations; calculate their speed.

the speed of an express train is x km/hr and the speed of an ordinary train is 12km/hr less than that of the express train. If the ordinary train takes one hour longer than the express train to cover a distance of 240km, find the speed of the express train.

a train travels 360 km at uniform speed. If speed had been 5km/hr more it would have taken 1h less for the same journey. Find the speed of the train.
