Two trains start from places A and B, respectively, and travel towards each other at the speeds of 60 km/h and 50 km/h, respectively. By the time they meet, the faster train has travelled 110 km more than the slower train. What is the distance between A and B?

A person walking at a speed of 7.2 km/h and crosses a bridge in 25 minutes. Find the length of the bridge (in metres)

An aeroplane covers a certain distance at a speed of 240 kmph in 5 hours. To cover the same distance in (5/3)hours, it must travel at a speed of:

If a person walks at 14 km/hr instead of 10 km/hr, he would have walked 20 km more. The actual distance travelled by him is:

The ratio between the speeds of two trains is 7 : 8. If the second train runs 400 km in 4 hours, then the speed of the first train is:
