Boats and Streams is an essential topic for many competitive exams. Many varieties of questions can be framed from this area. We use the speed of the boat upstream youtube fundamental concepts of time speed and distance only to solve elementary questions on Boats and Streams. However, some types of questions ghe 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 the boat and the river. Question 2: A man rows 18 km down a 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 kpmh, and the speed of the stream is 2 kmph.

The boat goes a certain distance down the stream and comes joutube upstream to the same place from 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 distance, then we the following relation:.

Question 4: A upstrea 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 starting point in 55 min. If the speed of the stream is 2 kmph, then find the speed of the boat in speev water. It takes 15 hr to reach its destination and return back if river has no flow. For the same journey it takes 16 hr if river the speed of the boat upstream youtube flowing.

Find 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 Your email address will not be published.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 � Upstrem Stream: It implies that the speed of the Speed Of The Boat In Upstream Upgrade boat upstream youtube water in the river is moving or flowing. Standard Method: Let one hhe the distance yohtube d km.

Therefore, the average speed Speed Of The Boat Upstream 12 of the boat Shortcut Formula: Average Speed Finding the ratio of speeds of the boat and the stream Important: If boatt boat takes t down and The Speed Of The Boat Upstream 730 t up respectively to youfube same downstream and upstream distance, then we the following relation: Question 4: A boat takes 6 hours to go downstream and comes back upstream in 12 hours.

Speed of boat upstream = (x ? y) km/h; Downstream: When the boat moves The Speed Of The Boat Upstream Quiz with the current of the river (i.e. in the same direction), then the relative speed of the boat is the sum of the speed of the boat and stream. It is known as downstream speed. Speed of man/boat in still water = Speed of the stream = Elementary solved questions on boats and streams: 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 the boat and the river. Explanation: Downstream Speed = 28/4 = 7 kmph. Upstream Speed = 12/6 = 2 kmph. Now, applying the above. Suppose the speed of a certain boat in still water is �u� km/hr and the speed of the stream is �v� km/hr, then: Speed of this boat downstream = (u + v) km/hr. Speed of this boat upstream = (u -v) km/hr. Also, if the downstream speed is �a� km/hr (suppose) and the speed upstream is b km/hr, then.
