Hey I am Ramandeep Singh. Do you want me to help you? Login Sign Up. Formula 1: If the ratio of downstream and upstream speeds is D: U, obat ratio of time taken will be U : D.
Question: A workwheet 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 boat and stream formula worksheet of the boat and speed of the water current respectively?
Solution: When 8 hours 48 minutes is written using mixed fractions. Therefore, the ratio of the time taken becomes Which on solving gives, Now, as the ratio of time is inversely proportional to that of Upstream and Downstream speeds. Speed of boat and stream formula worksheet, the ratio of speed of boat and the speed of stream will be. How far is the place? Solution: Take out the formula book.
A man rows a certain distance downstream in X speed of boat and stream formula worksheet and returns the same distance in Y hrs. Question: Ramesh can row a certain distance downstream in 6 hrs and returns the same distance in 9 hrs.
Formula 4: A man rows a certain distance downstream in X hrs and returns the same distance in Y hrs. Let us now jump to the questions, oof. A boat covers a distance of 30 km in 3 hrs in the direction of stream and covers same distance in 5 hrs in opposite direction of the stream. Find speed of the boat in still water. Therefore, in how much time will it cover a distance of 70 km downstream?
Find out his speed in still water. How much distance does he cover in 2 hrs during upstream? Stdeam much time will it take to cover km in still water? A man rows to a place at workshedt distance of Find the total time taken by.
A formu,a rows upstream 16 km oc downstream 28 km taking 5 hours each time. Find the velocity of the current. A can row a certain distance downstream in 6 hrs and return the same distance in 9 hrs.

Let "x" be the distance between A and B. M of 18, 20 is Multiply both sides by Divide both sides by So, the distance between A and B is km. Problem 4 :. A boat covers 24 miles upstream and 36 miles downstream in 6 hours while it covers 36 miles upstream and 24 miles down stream in 6. Find the speed of the stream.
Let "x" and "y" be speed upstream and downstream respectively. We can use the above formula and find the following times. Given : The boat covers 24 miles upstream and 36 miles downstream in 6 hours. Given : The boat covers 36 miles upstream and 24 miles downstream in 6. Adding 1 and 2 , we get,. Subtracting 1 from 2 , we get. Adding 3 and 4 , we get. Speed of the stream is. So, the speed of the stream is 2 mph.. Apart from the stuff given above, if you need any other stuff in math, please use our google custom search here.

Very important topic but is explained in nice way.
Saurabh Ghanghoriya Aug 11, Report. 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. For the same journey it takes 16 hr if river is flowing. Find speed of flow of river.
