The speed of first train is 45km/hr. and the speed of another train is 10m/sec. find the ratio of their speed?

A 900 metre long train crosses a 1200 metres long platform completely in 70 seconds. What is the speed of the train?

A train met with an accident 100 km from station P. It completes the remaining journey at 2/3 of the previous speed and reached 42 min late at station Q. If the accident had taken place 40 km further, it would have been only 22 min late. Then, what is the original speed of the train?

A train travelling at 36 km/h crosses a pole in 25 seconds. How much time (in seconds) will it take to cross a bridge 350 m long?

Length of train A is half as that of train B. Train A and B crosses the platform of length 100 meters in 5 seconds and 6 seconds respectively. If the ratio of speed of train A and B is 2 : 3, Find the length of train B.

Train A takes 1 hour more than train B to travel a distance of 720 km. Due to engine trouble speed of train B falls by one third, so it takes 3 hours more than Train A to complete the same journey. What is the speed of Train A (in km/hr)?

Speed of train B is 20% more than speed of train A and length of train A and B is 720 meters and 600 meters respectively. If both trains running in opposite direction cross each other in 24 second, then find speed of trains B (in km/hr)?

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?
