A boat goes 25 km upstream and 33 km downstream in 8 hours. It can also go 40 km upstream and 77 km downstream in 15 hours. Find the speed of the stream and that of the boat in still water.

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. Find the speed of the stream and that of the boat in still water.

A boat can go 20 km upstream and 30 km downstream in 3 hours. It can go 20 km downstream and 10 km .upstream in 1 2/3 hrs. Find the speed of the boat in still water and speed of stream.

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

The speed of a boat in still water is 10 km/hr. If it can travel 26 km downstream and 14 km upstream in the same time, find the speed of the stream.

A motor boat whose speed is 18 km/hr in still water takes 1 hour more to go 24 km upstream than to return downstream to the same spot. Find the speed of the stream.

A motor boat whose speed is 15 km/hour in still water goes 30 km downstream and comes back in a total time of 4 hours 30 minutes. Find the speed of the stream.

A car travels 20 km in 1 hour and another 40 km in 3 hour. What is the average speed of the car?

A man travels 370 km partly by train and partly by car. If he covers 250 km by train and the rest by car, it takes him 4 hours. But if he travels 130 km by train and the rest by car, he takes 18 minutes longer. Find the speed of train and that of car
