A boat covers 24 km upstream and 36 km downstream in 6 hours while it covers 36 km upstream and 24 km downstream in 6 hours. The velocity of the current is kmph 2 kmph. Jun 12, �� Upstream Speed = 15 + x. Downstream Speed = 15 � x. So, {30 / (15+x)} + {30 / (x)} = 4 ? (4 hours 30 minutes) ? { / (x2)} = 9/2. ? 9x2 = ?x2 = ?x = 5. Q 5. A boat is moving 2 km against the current of the stream in 1 hour and moves 1 . A boat takes Average Speed Of Boat In Upstream And Downstream Median 1 0 hours to travel 3 0 km upstream and 4 4 km downstream, but it takes 1 3 hours to travel 4 0 km upstream and 5 5 km downstream. Find the speed of the boat in still water and the speed . Boats and Streams - Quantitative aptitude tutorial with easy tricks, tips, Speed Upstream And Downstream 12 short cuts explaining the concepts. Online aptitude preparation material with practice question bank, examples, solutions and explanations. Video lectures to prepare quantitative aptitude for placement tests and competitive exams like MBA, Bank exams, RBI, IBPS, SSC, SBI, RRB, Railway, LIC, MAT. Very useful for freshers, engineers, software developers taking entrance exams.� 4) If you are given speed of the boat upstream and downstream and are required to find out the speed of the current, the following concept is very useful: Downstream Speed � Upstream Speed = 2 (Speed of the current) x + y � (x � y) = 2y. Halving this would give you the speed of the current. i.e. Speed of stream (y). (1. downstream speed of boat = sdownstream = v + c. Upstream data: d = 70 miles, t = hours. supstream = 70 miles/ hours = 70/ (miles/hr) = miles/hr. Downstream data: d = 70 miles, t = 5 hours. sdownstream = 70 miles/5 hours = 10/5 (miles/hr) = Boat Upstream And Downstream Problems Name 14 miles/hr. a).� Using our given info, we can use our distance formula to set up our 2 equations: 1. Our upstream given info is D = 70, R = v - c (speed going against the current), T = ; so our upstream equation is (v - c) = 2. Our downstream given info is D = 70, R = v + c (speed going with the current), T = ; so our downstream equation is (v + c) = Part (b): We can solve our two equations for c by the elimination technique (combining the two equations and eliminating the variable v). Speed Upstream = 7 km/hr. Recommended: Please try Speed Of The Boat Upstream And Downstream Path your approach on {IDE} first, before moving on to the solution. Approach: The direction along the stream is called downstream and the direction opposite the stream is called upstream. So in case of downstream the speeds will be added, while in case of upstream the speeds will be subtracted. The speed of boat downstream is equal to the sum of the speed of the boat in still water and speed of the stream. The speed of boat upstream is equal to the difference of the speed of the boat in still water and speed of the myboat113 boatplans: Speed Downstr.
