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

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.

The speed of a train is 4/7 of the speed of a car. The car covers 252 m. distance in 9 seconds. In what time will the train cover a distance of 64m.?

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?

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)?

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)?

A train moves at a speed of 35 km/h for the first 2 hours and at a speed of 50 km/h for the next 4 hours. Find the average speed of the train during the entire journey.
