A train covers 400 m distance in 24 sec. Its speed is-

Two train 120 meters and 160 meters in length are running towards each other on parallel lines at the speed of 70 kmph and 42 kmph respectively. How long will it take to cross each other after they meet?

The speed of two trains are in the ratio 6 : 7. If the second train covers 364 km in 4 hours, then what is the speed of the first train?

A 480 m long train takes 16 seconds to pass a pole. How long will it take to pass a platform that is 900 m long?

The speed of train A and train B is 93 km/hr and 51 km/hr, respectively. When both the trains are running in the opposite direction, they cross each other in 18 seconds. The length of train B is half of the length of train A. If train A crosses a bridge in 42 seconds, then find the length of the bridge.

Train A moving at speed 72 kmph crosses train B moving at 3/4th speed of train A in the same direction in 1 min and 26 seconds. The length of train A is 25/18th of the length of train B. What is the difference between the lengths of two trains?

A train of length 287 m, running at 80 km/h, crosses another train moving in the opposite direction at 37 km/h in 18 seconds. What is the length of the other train?

Two trains of lengths 100 m and 140 m respectively are running in opposite directions on parallel tracks. If their speed is 29 km/hour and 43 km/hour respectively. In what time will they cross each other?
