Short Tricks for Boat and Stream in Quant Section : SSC & Railway
Boats and streams -> important facts and formulae. I. In water, the direction along the stream is called downstream. And, the direction against the stream is called upstream. II. If the speed of a boat in still water is u km/ht and the speed of the stream is v km/hr, then: Speed downstream = (u + v) km/hr Speed upstream (u - v) km/hr. III. If the speed downstream is a km/hr and the speed upstream is b km/hr, then: Speed in strill water = 1/2 (a + b) km/hr Rate of stream = 1/2 (a - b) km/hr. Boats and streams -> solved examples. 1. In a stream running at 2 kmph, a motorboat goes 6 km up. Boats and Streams questions require concepts and formula of time speed and distance. However, various tricks and shortcut formulas are handy to save time.� 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. Boats and Streams � Terminologies: Stream: It implies Boat And Stream Problems In Tamil Code that the water in the river is moving or flowing. Downstream or with the stream: It indicates that the stream favors the man�s rowing (or boating). i.e., Boat And Stream Problems Formula Questions the direction of rowing and direction of flow (stream) is same. Let us try to solve all the different kinds of examples of Boats and Streams in this section on Stream Boat Problems Practice Questions.� Let us start by recalling some of the formulas for this section. 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.

When we move upstream, our speed gets deducted from the speed of the stream. Similarly when we move Boat And Stream Problems Formula Array downstream our speed gets added. Example 1: A boat travels equal distance upstream and downstream.

What is the speed of the boat in still water? Example 2: A boat travels equal distance upstream and downstream. What is the speed of the current? Example 3: 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. Solution: Downstream speed is ,.

Speed of current Downstream�Upstream speed. When the river is running at 1. How far is the place? A man rows a certain distance downstream in X hours and returns the same distance in Y hours. Example 5: Vikas can row a certain distance downstream in 6 hours and return the same distance in 9 hours.

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. Still water: It implies that the speed of water is zero generally, in a lake. Quicker Method to solve the Questions.

Let the required distance be x km. Solution: Let the width of the river be x. Let a, b be the speeds of the ferries. Home G. Maths Reasoning Computer English.
