Boats & Stream Tricks with Questions - BankExamsToday
1. Boats and Streams Formulas and Facts. 1. Boat going Downstream: If boat is going in the direction of water flow then it is called boat going downstream. 2. Boat going Upstream: If boat is going opposite to the direction of water flow then it is called boat going upstream. 3. Speed Downstream: If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then: Speed downstream = (u + v) km/hr. Means the speed of stream and of boat will be added. 4. Speed Upstream: If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then: Speed u.

Learn and take practice tests!� If we see the above formula closely, we see that adding upstream and downstream speeds gives us 2x, which is twice the speed of the boat, i.e. [x + y + x � y] = 2x. If you just remember this concept, you won't need to remember and recall the above formula while solving the problems. Boats and Streams Questions with Explanation. When the boat goes against the current of the river is referred to as Upstream. In other words, the direction against the river current is called upstream. If the speed of motorboat in still water is x km/hr and the speed of stream is y km/hr then Upstream Speed = (x - y) km/hr. When the boat goes with the current of the river is referred to as Downstream. In other words, the direction along the river current is called downstream.� In that case, use the below formula to Boat And Stream Questions Formula Key get the answer- Let downstream speed is a km/hr and upstream speed is b km/hr then, Speed of boat in still water. a + b 2. Speed of stream. a - b 2. Trick 1 The speed of a boat in still water is x km/hr.

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, then ratio of time taken will be U : D. Question: A boat 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 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. Now, 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 hrs 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, 1. 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? How much time will it take to cover km in still water? A man rows to a place at a distance of Find the total time taken by him. A man rows upstream 16 km and 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. Labels: quant , quantitative. Newer Post Older Post Home. Can I help you? Join my class here Follow me:. Close Menu.
