# Practice Test -Boats and Streams Aptitude

1. Speed of a boat in standing water is 9 kmph and the speed of the stream is 1.5 kmph. A man rows to a place at ‘a distance of 105 km and comes back to the starting point. The total time taken by him is:

2. A boat covers 24 km upstream and 36 km downstream in hours while it covers 36 km upstream and 24 km downstream in 6 ½ hours. The velocity of the current is:

3. A man can row at 5 kmph in still water. If the velocity of current is 1 kmph and it takes him 1 hour to row to a place and come back, how far is the place?

4. A man takes twice as long to row a distance against the stream as to row the same distance in favour of the stream. The ratio of the speed of the boat (in still water) and the stream is:

5. A boat takes 19 hours for travelling downstream from point A to point B and coming back to a point C midway between A and B. If the velocity of the stream is 4 kmph and the speed of the boat in still water is 14 kmph, what is the distance between A and B?

6. In one hour, a boat goes 11 km along the stream and 5 km against the stream. The speed of the boat in still water (in km/hr) is:

7. A motorboat whose speed is 15 km / hr in still water goes 30 km downstream an: comes back in a total of 4 hours 30 minutes. The speed of the stream (in km / hr) is

8. A man rows to a place 48 km distant and back n 14 hours. He finds that he can row 4 km with the stream in the same time as 3 km against the stream. The rate of the stream is:

9. A boat takes 90 minutes less to travel 36 miles downstream than to travel the same distance upstream. If the speed of the boat in still water is 10 mph, the speed of the stream is:

10. A boat running downstream covers a distance of 16km in 2 hours while for covering the same distance upstream, it takes 4 hours. What is the speed of the boat in still water?

Things to remember: Boats and Streams

There are four things that play an essential role in any question related to boats and streams section in a quantitative aptitude test.

Still water: The water in a water body or a river under consideration which is not flowing can be defined as still water.

Stream: This term represents flowing water in a river, and it generally moves with certain mentioned speed.

Upstream: When the swimmer or the boat is moving against the flow or stream; he is said to be moving upstream.

Downstream: When the swimmer or the boat is flowing in the direction of water/ stream, it is defined as downstream.

Few important points that you should remember while solving these questions are:

When the speed of the swimmer or boat is defined as X km/hr and the overall speed of the flow or stream is given as Y km/hr:

• The speed of the swimmer or boat towards the stream or the speed downstream is defined as:

Speed downstream = (X + Y) km / hr

• The speed of the swimmer or boat against the flow or stream or the speed upstream is given as:

Speed upstream = (X - Y) km / hr

This information can help you to make a quick analysis of quantitative aptitude test questions.
