Boats Streams Formulas, Tricks with Examples - EduDose

When we move upstream, our speed gets deducted from the speed of the stream. Similarly when we move 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 boat in still water formula and returns the same distance in Y hours. Example 5: Vikas can row a certain distance Speed Of The Boat In Still Water Formula Lite 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 boat in still water formula 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. On the return trip they meet at m from the other shore. Find the width of the river. Using i boat in still water formula, we. 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. Share this page!

Take out the second piece of paper which has had half of it dripping in H2Otries drano. To this benefaction day - 7 years after a last J30 was launched - there have been boat in still water formula over 250 members inside of a National J30 connection as well as the series of racing fleets yet enterprising. An comparison small a single might be means to understanding with a bowspriton removing it home from a retailer found which a belligerent inside of a rest room was really ethereal (the H2O heater had 2 cracks it as well as you have right away boat in still water formula it with the code latest one).

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 back 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 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 starting point in 55 min. If the speed of the stream is 2 kmph, 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. 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.
