A fast train takes 3 hours less than a slow train for a journey of 600 km. If the speed of the fast train 10 km/hr higher than that of slow train, then find the speed of the slow train.

A train running at the speed of 80 km/h crosses a 350 m long tunnel in 36 seconds. The length of the train (in m) is:

The ratio between the speeds of two train is 2 : 5. If the first train runs 350 km in 5 hours, then the difference between the speeds (in kmph) of both the trains is:

A train running at a speed of 45 km/h crosses a 100 m long platform in 60 seconds. The time taken by the train to cross an electric pole is:

Which of the following speeds is maximum ?

A boy travels between point A and point B at a speed of 6 km/h and returns at a speed of 9 km/h. If the total time taken by him is 1 hour 15 min, the distance between A and B is:

A, B and C are in a cycle race of 1500 meters. A cycles twice as fast as B, C cycles $\frac{1}{2}$ as fast as B, C completes the race in 40 minutes. Then, where was B from the finishing line when A finished the race?
