Two trains of equal length, running with the speeds of 60 and 40 kmph, take 50 seconds to cross each other while they are running in the same direction. What time will they take to cross each other if they are running in opposite directions ?
The distance between the two railway stations is 1176 km. To cover this distance, an express train takes 5 hours less than a passenger train while the average speed of the passenger train is 70 km/h less than that of the express train. The time taken by the passenger train to complete the travel is:
A train travels the distance between stations P and Q at a speed of 126 km/h, while in the opposite direction it comes back at 90 km/h. Another train travels the same distance at the average speed of the first train. The time taken by the second train to travel 525 km is:
Train ‘A’ runs at a speed of 80 kmph and leaves station ‘X’ at 11.00 a.m. Train ‘B’ leaves station ‘X’ at 11.15 a.m.in the same direction, on the same day . At what speed train ‘B’ should run in order to catch train ‘A’ at station ‘Y’ located at a distance of 60 km?
