What is Boats and Streams Questions?
There is a wide range of concepts about boats and streams problems. Some of the major concepts related to boats and streams are mentioned below:
- Stream – A stream is used to refer to running river water.
- Upstream – When the boat rows or moves in the opposite direction of the flow of the stream, it is said to be moving upstream. The boat’s net speed, in this case, is upstream speed.
- Downstream – When the boat rows or moves along the direction of the flow of the stream, it is said to be moving downstream. The boat’s net speed, in this case, is downstream speed.
- Still Water – Still water is the assumption of water being still or stationary. This happens when the speed of the water is zero.
Important Boats and Streams Topics
- Stream – The stream is the moving water in a river-like water body.
- Still Water – As the name suggests, this is when the speed of the stream is zero, and water is considered to be stationary.
- Upstream – When the boat is flowing in the opposite direction of the stream, it is called upstream. Upstream speed = (u-v) km/hr (where “u” is the speed of the boat in still water, and “v” is the speed of stream).
- Downstream – When the boat is flowing along the direction of the stream, it is called downstream.
- Downstream speed = (u+v) km/hr
- Average Speed of the Boat – Calculate the Upstream Speed (U) and the Downstream Speed (D). Multiply them and divide them by still water.
- Speed of Man in Still Water – If you know that the boat has travelled a distance downstream in “t1” hours and time “t2” is taken to return the same distance. If “v” is the speed of the stream, then the speed of man in still water is [v x {(t2 + t1)/(t2-t1)}] km/hr.
- Distance Travelled by Boat – If “u” is the speed of the boat in still water and “v” is the speed of the stream, then the distance would be the difference of squares of the two; multiply it by the time given and divide the result by 2v or 2u, as required.
Formulas for Upstream and Downstream Problems
Below are the important formulas for the various boats and streams concepts. To calculate,
- Upstream = (u−v) km/hr
- Boat’s speed in still water = ½ (Downstream Speed + Upstream Speed)
- Downstream = (u+v)Km/hr
- Boat’s average speed = {(Upstream Speed x Upstream Speed)/Boat’s Speed in Still Water}
- Stream’s Speed = ½ (Downstream Speed – Upstream Speed)
- Boat’s Speed (Still Water) = ½ (Downstream Speed + Upstream Speed)
- Distance (X) between two points, when the time taken to come back to the starting point is ‘t’ = {(u2-v2) x t } / 2u.
- Distance (X) between two points situated upstream and downstream when the time taken to cover going back and forth is ‘t’ = {(u2-v2) × t} / 2v.
Tips & Tricks to solve the Boats and Streams
Some important tricks and tips for solving boats and streams questions are:
- The first step to solving the boats and streams problems is to thoroughly read the question with a calm mind. This helps understand the various terms behind the boats and stream concepts being applied.
- If upstream and downstream are not mentioned, do not be confused. You should remember that motion opposite to the flow of the stream is upstream and motion along the flow of the stream is downstream.
- Do not forget to memorise the formulas related to boat and stream problems. Regularly going through the formulas will help memorise them. Knowing the exact formula required for a particular question helps solve the question easily.
- The last, but not the least, a tip is constant practice. You will be able to solve the questions easily if you have been in practice.
