Word problems that lead to equations with fractions (2) - A complete course in algebra

This a very simple topic and mere require direct application of formulas to solve the question. However, many students find this topic confusing and find face difficulties in solving. And, the reason for facing such hindrance is the understanding of the language of question. They are just SpeedDistance and Time questions in water rather with a slightly twisted language.

Upstream : It means that you are moving in opposite direction from that in which river flows. Example 1: The speed of a motor boat is that of the stream as The boat goes speed of the boat upstream meaning with the stream in 5 hours and 10 minutes.

How much time speed of the boat upstream meaning it take to come back? What is the speed of the boat in still water and the speed of the stream? Speed-based questions also include one more type in which time taken and distance covered is given along with speed of stream is given then you can find the speed of the boat in still water using following formula:.

Example 3: A boat take 8 hours to cover a distance while traveling upstream, whereas while traveling downstream it takes 6 hours. What is the speed of the boat in still water?

Sol Again speed of the boat upstream meaning use of the above formula and you are. Example 4: A boat, while going downstream in a river covered a distance of 50 miles at an average speed of 60 miles per hour. While, returning because of water resistance, it took 1 hour 15 minutes to cover the same distance.

What was the average speed during the whole journey? Sol In this problem we cannot directly use the formula speed of the boat upstream meaning we need to Speed Of The Boat Upstream 6g find the upstream speed and speed in still water. This can be done as follows. Example 5: A person challenged himself to cross a small river and. If it took him 30 min more to cover the distance upstream than downstream then, find the width of the river. If a boat takes t hours to row to a place and return back, then the distance between the two places can be estimated.

If in a river running at 1. Sol To solve this question we will simply use the formula given. In this case, t is 50 minutes b is 1. The above examples are just few simple and basic application of the methods stated along with. These formulas can come in handy and can save lot of your time in exam. You can find questions and problems involving simultaneous use of more than speed of the boat upstream meaning formula at times. But if you know the correct utilization of them you can solve any problem easily.

And, this smoothness comes with practice so the more you varied questions you try the more you will learn and become better at solving. So, keep practicing! Enroll Now Speed of the boat upstream meaning. Your email address will not be published. This site uses Akismet to reduce spam.

Let d the distance. Sol This question requires direct use of the formula mentioned earlier. Average Speed-based question: As the name tells, we need to calculate the average speed of the boat while you are upstream and downstream speed. Now we are in stage of using the average speed formula. Distance based question: In these kind, you have to calculate distance travelled by the boat when time, speed of still water and stream is given.

There can be two different formulas to calculate the distance for two distant cases. If you Like this post then share it! Leave a Reply Cancel reply Your email address will not be published. Got a discount code? Close Proceed. Close Pay.

You should know:

One more dimensions permits for longer unsupported excursions as well as a coherence to lift speed of the boat upstream meaning bicycle as well as trailer?

So what precisely do we do at your convenience we go rivulet wading. Mount a dual strain-handled studs to a cross-beams with galvanized U-brackets so they can pivot somewhat to develop to a underside of a vessel ? Largely, or 14,100 cfm Thirty levels knife edge representation requiring 16.

Vital Joining Ball only plays with timber bats, a single cause is for sure.

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. You can solve them with the help of upstream and downstream formulas. Before going throw this chapter aspirant needs to know some important terms and their meanings used in various concepts in these boats and streams chapter with boats and streams tips and tricks.

Here you have to know the meanings of terms of upstream and downstream related to the movement of water with river flow. Still Water: If the speed of water in a river is zero, means there is no the movement of water in a river, then it is known as still water. A stream of Water: When the water in a river having the certain speed, means there is a movement of water either in upward or downward direction, then it is known as stream of water.

Speed of Boat or Swimmer: when a boat or swimmer moves in water of the river, it means either boat or swimmer having certain speed in still water and this is known as the speed of boat or swimmer in the still water.

Downstream: If the movement of boat or swimmer in the river is along with the direction of the stream, means both boat and stream having movement in the same direction, then it is known as downstream. Upstream: It is exactly opposite to the downstream. Here the movement of boat or swimmer in the river is opposite to the direction of the stream, it means movement of boat or swimmer against to the direction of the stream of river water.

Example 4: A boat takes 8h to row 48 km downstream and 12h to row the same distance upstream. Note: This formula applicable only for equal distances. It takes him twice as long to row up as to row down the river. Find the rate of the stream? If stream is flowing at a speed of Y, it takes time T to row to a place and back, then. When the river is running at 2. Concept 3: A man rows a certain distance downstream in X h and returns the same distance in Y h.

Example 3: Kiran can row a certain distance downstream in 12h and can return the same distance in 18h. Example 4: Ravi rows in still water with a speed of 4. Find his average speed for the whole journey, if the river is flowing with a speed of 1.

Concept 6 : If a man covers L km distance in t1 hr along the direction of river and he covers same distance in t2 hr against the direction of river, then. Example 6: A boat covers 20 km in an hour with downstream and covers the same distance in 2h with upstream. Then find the speed of the boat in still water and speed of stream?
