One airplane travels due north at 300km/h and another airplane travels due south at 300 km/h. Are their speeds the same ? Are their velocities the same ? Explain.

A person 'P' in train moving due south with 80 kmph and his friend Q moving due west at 60 kmph Q finds that P is travelling with a velocity of

An aeroplane leaves an airport and flies due north at a speed of 1000 kmph. At the same time another aeroplane leaves the same airport and flies due west at a speed of 1200 kmph. How far apart will the two planes be after 1 1/2 hour?

A motor car is going due north at a speed of 50 km/h. It makes a 90^(@) left turn without changing the speed. The change in the velocity of the car is about.

A train travels a distance of 480 km at a uniform speed. If the speed had been 8km/h less, then it would have taken 3 hours more to cover the same distance. We need to find the speed of the train.

A loaded truck travels 14 km in 25 minutes. If the speed remains the same, how far can it travel in 5 hours?

Places A and B are 120 km apart on a highway. One car starts from A and another from B at the same time at different speeds. If the cars travel in the same direction, they meet in 1 hour. If they travel towards each other, they meet in 2 hours. What are the speeds of the two cars?

Places A and B are 150 km apart on a highway. One car starts from A and another from B at the same time at different speeds. If the cars travel in the same direction, they meet in 6 hours. If they travel towards each other, they meet in 2 hours. What are the speeds of the two cars?
