Two trains of length 200m and 160m respectively are running on parallel lines of rails. When running in the same direction the faster train passes the slower one in 36 seconds, but when they are running in opposite directions with the same speeds as earlier, they pass each other in 18 seconds. Find the speed of each train?

Let the speed of the faster train and slower train is x m/sec and y m/sec When running in the same direction (x – y) × 36 = (200 + 160) = 360………….(i) When running in opposite directions (x + y) × 18 = (200 + 160) = 360………….(ii) From (i) and (ii) x = 15, y = 5

- Without stopping the speed of the train is 125 kmph, with stopping the speed of the train is 75 kmph.Find the stop time of the train?
- A train can cross a pole in 36 seconds. While if the train increased its speed by 50% then time taken by it to cross 324 metres long platform is 42 seconds. Find the time taken by the train to cross a 120 metre long tunnel.
- Two trains are running on parallel lines in the same direction at the speed of 76 km/h and 40 km/h respectively. The faster train crosses a man in the slower train in 55 second. If the length of the slower train is 7/11th of the faster train, then find the length of the slower train.
- A train started from station P and preceded towards station Q at a speed of 90 km/h. 42 minutes later, another train started from station Q and preceded towards station P at 100 km/h. If the distance between the two stations is 443 km, at what distance from station P will the trains meet?
- A person sees a train passing over 2 km long bridge. The length of the train is half that of bridge if the train clears the bridge in 6 mins. What is the speed of the train?
- A train crosses a stationary pole in 6 sec and a 70 m long platform in 13 secs. What is the length of the train?
- Train A running at speed of 54 km/hr crosses a platform having twice the length of train in 12 sec. Train B whose length is 240m crosses same platform in 18 sec, then find the speed of train B ?
- A goods train leaves a station at a certain time and at a fixed speed. After 11 hours, an express train leaves the same station and moves in the same direction at a uniform speed of 126 km/hr, this train catches up the goods train in 7 hours. Find the speed of the goods train.
- Time is taken by two trains running in opposite directions to cross a man standing on the platform in 24 seconds and 14 seconds respectively. It took 20 seconds for the trains to cross each other. What is the ratio of their speeds?
- A train whose speed is 40 m/s crosses a bridge in 20 seconds. Another train which is 80m shorter than the first train crosses the same bridge at the speed of 72 km/hr. Find the time taken by the second train to cross the bridge.
