A motorboat goes a down stream in a river and covers the distance between two coastal towns in five hours. It covers this distance upstream in six hours. If the speed of the stream is 4 2 km`//`hours find the speed of the boat in still water.

A motorboat goes down stream in a river and covers the distance between two coastal towns in five hours. It covers this distance upstream in six hours. If the speed of the stream is 2 km/hour find the speed of the boat in still water.

An aeroplane covers a certain distance at a speed of 240 kmph in 5 hours. To cover the same distance in 1 hours, it must travel at a speed of:

Formulate the following problem as a pair of equations and then find their solutions. A boat goes 30 km upstream and 44 km downstream in 10 hours. In 13 hours it can go 40 km upstream and 55 km downstream. Determine the speed of the stream and that of the boat in still water.

formulate the following problem as a pair fo equations and then find their solution. A boat goes 28 km upsteam and 39 km downstream in 7 hours, In 8 hours it can go 21 km upstream and 65 downstream. Determine the speed of the stream and speed of the boart in still water.

Formulate the following problems as a pair of equations and then find their solutions. A boat goes 32 km upsteam and 60 km downstream in 9 hours. In 11 hours it can go 40 km upstream and 72 km downstream. Determine the speed of the stream and that of the boat in still water.

A cyclist covers a distance of 28 km in 2 hours. Find the time taken by him to cover a distance of 56 km with the same speed

A car covers a distance of 89.1 km in 2.2 hours. What is the average distance covered by it in 1 hr.

A train moving at a constant speed covers distance of 90 km in 2 hours. Find the time taken by the train to cover a distance of 540 km at the same speed.

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.
