A man can rowdownstream a distance of 9 km in 2 hours and takes 6 hours while returning to the starting point. What is the speed (in km/h) of the stream?

A speed ramp at an airport is a moving conveyor belt on which you can either stand or walk. It is intended to get you from place to place more quickly. Suppose a speed ramp is 120 m long. When you walk at a comfortable speed on the ground, you cover this distance in 86 s. When you walk on the speed ramp at this same comfortable speed, you cover this distance in 35 s. Determine the speed at which the speed ramp is moving relative to the ground.

Distance between two stations A and B is 690 km. Two cars start simultaneously from A and B towards each other, and the distance between them after 6 hours is 30 km. If the speed of one car is less than the other by 10 km/hr, find the speed of each car.

A car starts from rest and accelerates uniformly to a speed 50ms^(-1) over a distance of 250m . Find the acceleration and time taken by the car to cover this distance.

A and B started simultaneously towards each other from P and Q respectively . The distance between P and Q id 600 km and the ratio of speeds of A is to B is 5:7. if they meet at a point M: find the distance PM.

A ball is projected for maximum range with speed 20 ms^-1 . A boy is located at a distance 25 m from point of throwing start run to catch the ball at the time when the ball was projected. Find the speed of the boy so that he can catch the ball (Take g = 10 ms^-1) .

A steamer goes downstream and covers the distance between two ports in 5 hours while it covers the same distance upstream in 6 hours. If the speed of the stream is 1 km/hr, find the speed of the steamer in still water.
