Boats and Boats And Streams Aptitude Formulas Subject Streams - Aptitude Questions and Answers Jan 09, �� Basic Formulas If speed of boat in still water is b km/hr and speed of stream is s km/hr, Speed of boat in downstream = (b + s) km/hr, since the boat goes with the stream of water. Speed of boat in upstream = (b - s) km/hr. Jan 12, �� Formulas for Boats And Streams Questions In Aptitude Boats and streams is one of the most common topics in quantitative section of all the job entrance myboat304 boatplans is also included in Aptitude section of many job test in companies like TCS, Infosys etc. This a very simple topic and require to direct application of Formulas to solve the question. If the speed of motorboat in still water is x km/hr and the speed of stream is y km/hr then Downstream Speed = (x + y) km/hr In the question, you will be given downstream speed and upstream speed and asked for speed of a boat in still water and the speed of the current. In that case, use the below formula to get the answer-.

This article explains how to solve boats and streams problems easily and quickly. The types of questions that can be expected from quantitative aptitude section of boats and streams include following. The key point here is you can solve any of these questions using the formulas and short cuts given below.

Formulas and short cuts given below are also applicable to problems involving. Find the speed of stream and speed of boat in still water. Scenario 2 : A man can row a boat, certain distance downstream in td hours and returns the same distance upstream in tu hours. Last but not the least, practice as many question as you can to gain better understanding of these formulas and to improve your speed in solving them. Here is a sample set of solved quantitative aptitude questions based on boats and streams.

A boat running downstream covers a distance of 16 km in 2 hours while for covering the same distance upstream, it takes 4 hours. What is the speed of the boat in still water? The Speed of a boat in still water is 10 kmph. If it can travel downstream 20 kms in the same time as it can travel 12 kms upstream.

What is the speed of the current? The Speed of a boat in still water is 20 kmph. If it can travel 16 km upstream in 1 hr. A man can row three-quarters of a kilometer against the stream in 11 minutes and return in. A boat running upstream takes 8 hours 48 minutes to cover a certain distance, while it takes 4 hours to cover the same distance running downstream. What is the ratio between the speed of the boat and speed of the water current respectively?

The effective speed of travel of a boat downstream is 20 kmph whereas it is 10 kmph upstream. His speed in still water is:. Note: as the object moves along with the water, the stream helps the object. So, the down stream speed DS is. Upstream: when the boat moves in the direction opposite to the that of the current is called against the stream or against the current or upstream. Note: as the object moves against the water pushes the object in opposite direction. So, the upstream speed US is.

If the speed of the stream is 3kmph, what is the speed of the boaat in still water? Solution: Let the speed of the boat in still water be x kmph. If it can travel 26km downstream and 14km upstream in the same time , the speed of the stream is? The distance traveled downstream in 12 minutes is?

Question 4: A man takes twice long to row a distance against the stream as to row the same distance in favor of the stream. Your email address will not be published.

You have already completed the quiz before. Hence you can not start it again. Example 6: Two ferries start at the same time from opposite sides of a river, travelling across the water on routes at right angles to the shores. Each boat travels at a constant speed though their speeds are different. They pass each other at a point m from the nearer shore.

Both boats remain at their sides for 10 minutes before starting back. On the return trip they meet at m from the other shore. Find the width of the river. Using i , we get. Using ii ,. Stream: It implies that the water in the river is moving or flowing.

Upstream: Going against the flow of the river. Downstream: Going with the flow of the river.
