Boats and Streams downstfeam an essential topic for many competitive exams. Many average speed of boat in upstream and downstream name of questions can be framed from this area.

We use the fundamental concepts of time speed and distance only to solve elementary questions on Boats and Streams. However, some types of questions are tricky and take lots of time to solve by applying textbook approach.

Fortunately, there are some shortcut formulas available to handle such problems. In this article, besides an understanding of the basic concepts of boat sand streams, we will also learn few tricks to solve some exceptional questions. Some shortcut formulas related to the speed of boats and streams is handy as we require them frequently.

Below are the lists of the formulas:. Question 1: A boat is rowed down a river 28 km in 4 hours and up a river 12 km in 6 hours.

Find the speed of nae boat and the river. Question 2: A man rows 18 km down o river in 4 hours with the stream and returns in 12 hours. Find his speed and also the speed of the stream. Question The speed of the boat in the still water is 6 spsed, and the speed of the stream is 2 kmph.

The boat goes a certain distance down the stream and comes back upstream to the same place upstrfam where it started. Find the average speed of the boat in the entire journey. Average Speed. Important: If the boat takes t down and t up respectively to travel same downstream and upstream Boat Traveling Upstream And Downstream Update distance, then we the following relation:.

Question 4: A boat takes 6 hours to go downstream and comes back upstream in 12 hours. Find the ratio of the speed of the boat and the speed of the stream. Question 5: A man rows 10 km upstream and back again to the downnstream point in 55 min.

If the speed of the stream is 2 speex, then find the speed of the boat in still water. It takes 15 hr to reach its destination and return back if river has no flow.

Average speed of boat in upstream and downstream name the same journey it takes 16 hr if river is flowing. Zverage speed of flow of river. Your email address will not be published. Skip to content Boats and Streams is an essential topic for many competitive exams.

Boats and Streams � Terminologies: Stream: It implies that the water in the river is moving or flowing. Standard Method: Let one side average speed of boat in upstream and downstream name distance be d km. Therefore, the average speed of the boat Shortcut Formula: Average Speed Finding the ratio of speeds of the boat and the stream Important: If the boat takes t down and t up respectively to travel same downstream and upstream distance, then we the following relation: Question 4: A boat takes 6 hours to go downstream and comes back upstream bat 12 hours.

Standard Method: Let the common distance upsgream d km. Finding the total time of the journey. Shortcut Formula: Let the speed of the boat in still water be x kmph. Leave a Comment Cancel Reply Your email address will not be published. Join Now.

Dec 11, �� Approach: The direction along the stream is called downstream and the direction opposite the stream is called upstream. So in case of downstream the speeds will be added, while in case of upstream the speeds will be subtracted. The speed of boat downstream is equal to the sum of the speed of the boat in still water and speed of the stream.
