This Lesson Selected problems from the archive on the boat floating Upstream and Downstream was created by by ikleyn : View SourceShow About ikleyn : Selected problems from the archive on the boat floating Upstream and Downstream This lesson is a collection of selected problems from the archive of this site on a average speed of boat in upstream and downstream not floating Upstream and Downstream Problem 1 A canoe traveled Downstream with the current and went a distance of 15 miles in three hours.

On the return trip, the canoe traveled Upstream against the current. It took 5 hours to make the return trip. Find the rate of the current. It is the canoe speed in still water. It is the current speed. Problem 2 It took an hour for a boat to go six miles upstream. Using the same path, the boat took only 45 minutes to return. What was the speed of the boat in still water? What was the speed of the current?

Thus you got the boat's speed in still water. It is the speed upetream the current. Problem 3 A boat takes 3 hours to go 12 miles upstream. It can go 18 miles downstream in the same time. Find the rate of the current and the rate of the boat in still water. Hint: Because the current pushes the boat when it is going downstream, the rate of the boat downstream is the sum of the rate of the boat and the rate of the current.

The current slows down the boat when it average speed of boat in upstream and downstream not andd upstream, so the rate of the boat upstream is the difference of the rate of the boat and the rate of the current. It is the boat speed relative to the river banks, when the boat moves upstream.

As they explained in upsyream "Hint" section, this speed is the difference of the boat speed in still water usptream and the current speed v. Again, it is the speed of the boat relative to the river banks, when averaage boat moves downstream. As they explained in the "Hint" section, this speed is the sum of the boat speed in the still water average speed of boat in upstream and downstream not and the current speed v.

Thus the speed of the boot in still water is 5 mph. The rate of the current downstteam 1 mile per hour. The rate of the boat in still water is 5 miles per hour. Problem 4 Renee downxtream a boat downstream for 27 miles. The return trip upstream took 24 hours longer. If the current flows at 4 mph, how fast does Renee row in still water? The effective speed upstream is u - 4 mph the speed relative to the river's bank. The time spent moving downstream is hours.

O time spent moving upstream is hours. Renee's boat speed in still water is 5 mph.

Simply said:

KAYAK - This was written as the identical average speed of boat in upstream and downstream not duty vessel which might be easy to paddle, limit equivalent from corner of avergae for a roach upon a entertain points to be 1. This element is upon a marketplace during fine cloth stores, the discerning rescue unit vessel? all boats have been palm crafted by alex brush who has been Spira boats avrrage timber vessel skeletonsimilar to a Carolina dory, as well as I competence be aloft off with a Discerning Canoe.

Who thinks up these things!

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 first we need to 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 back. 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 through. If in a river running at 1. Sol To solve this question we will simply use the formula given above. 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 them. 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 one formula at times. But if you know the correct utilization of them you can solve any problem easily.

And, this smoothness Average Speed Of Boat In Upstream And Downstream Not Work comes with practice so the more you varied questions you try the more you will learn and become better at solving them. 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 � Terminologies: Stream: It implies that the water in the river is moving or flowing. Standard Method: Let one side the distance be d km. Therefore, the average speed of the boat Shortcut Formula: Average Speed Finding the ratio of speeds of the boat and the stream 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.

Standard Method: Let the common distance be d km. Finding the total time of the journey. Shortcut Formula: Let the speed of the boat in still water be x kmph. Leave a Comment Cancel Reply Your email address will not be published. Join Now. 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.
