Problems On Trains

41 A train 125 m long passes a man, running at 5 km/hr in the same direction in which the train is going, in 10 seconds. The speed of the train is

42 Two trains of lengths 80 m and 90 m are moving in opposite directions at 10 m/s and 7 m/s, respectively. Find the time taken by the trains to cross each other:

43 In what time will a train 100 m long cross an electric pole, if it's speed be 144 km/hr?

44 Two trains running at the rate of 45 km and 36 km an hour respectively, on parallel tracks in opposite directions; are observed to pass each other in 8 seconds, and when they are running in the same direction at the same rate as before, a person sitting in the faster train observes that he passes the other in 30 seconds. Find the length of trains:

45 A jogger running at 9 km/hr alongside a railway track is 240 m ahead of the engine of a 120 m long train running at 45 km/hr in the same direction. In how much time will the train pass the jogger?

46 A 270 m long train running at a speed of 120 km/hr crosses another train running in opposite direction at the speed of 80 km/hr in 9 seconds. What is the length of the other train?

47 A 300 m long train crosses a platform in 39 seconds, while it crosses a signal pole in 18 seconds. What is the length of the platform?

48 A 220 m long train is running at 120 km/h. In what time, will it pass a man running in the direction opposite to that of the train at 12 km/h?

49 A 440 m long train is running at 240 km/h. In what time will it pass a man running in the direction opposite to that of the train at 24 km/h?

50 Two trains of lengths 50 m and 65 m are moving in the same direction at 18 m/s and 17 m/s, respectively. Find the time taken by the faster train to cross the slower train:
