Nov 21, �� where �u� is the speed of the boat in still water and Speed Of The Boat Going Upstream And Downstream �v� is the speed of the stream. If it takes �T� hours more Average Speed Of Boat In Upstream And Downstream Quarter to go to a point in upstream than downstream for the same distance, then the distance = {(u2-v2) ? t} / 2v, where �u� is the speed of the boat in still water and �v� is the speed Estimated Reading Time: 2 mins. Jun 12, �� Speed of a boat in still water = ? (DownstreamSpeed + UpstreamSpeed) Speed of boat in still water = ? (13+7) = ? ? 20 = 10 km/hr. Q 3. A woman can row upstream at 16 km/hr and downstream at 26 km/hr. What is the speed of the stream? 5 km/hr; 2 km/hr; km/hr; 21 km/hr; 12 km/hr; Answer: (1) 5km/hr. Solution: According to the formula,Estimated Reading Time: 4 mins. The net speed of the boat in this case is called upstream speed. Let the speed of the boat in still water is 'b' km/hr and the speed of the stream is 'w' km/hr. When the boat goes downstream then the speed will be (b + w) km/hr as in this case the water will take the boat along with it. When the boat goes upstream then the speed will be (b - w) km/hr as in this case the water will offer resistance to the boat.
Asymptotic Analysis. Worst, Average and Best Cases.� In order to calculate the speed of the boat upstream and downstream, we should know the speed of the boat in still water(B) and speed of the stream (S). Examples: Input: B = 10, S = 4 Output: Speed Downstream = 14 km/hr.� 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. Boats and Streams � Terminologies: Stream: It implies that the water in the river is moving or flowing. Downstream or with the stream: It indicates that the stream favors the man�s rowing (or boating). i.e., the direction of rowing and direction of flow (stream) is same.� Finding average speed if moving with different upstream and downstream speeds. Important: If a man capable of rowing at the speed of x m/sec in still water, rows the same distance up and down a stream flowing at a rate of y m/sec, then his average speed throughout the journey is. Question The speed of the boat in the still water is 6 kpmh, and the speed of the stream is 2 kmph. The boat goes a certain distance down the stream and comes back upstream to the same place from where it started. A boat travelled upstream a distance of 90 miles at an average speed of (v-3) miles per hour and then travelled downstream at an average speed of (V+3) miles per hour. If the trip upstream took half an hour longer than the Average Speed Of Boat In Upstream And Downstream Values trip downstream, how many hours did it take the boat to travel downstream? A) b) C) D) e) � If Average Speed Of Boat In Upstream And Downstream Map the trip upstream took a half hour longer than the trip downstream, then how many hours did it take the boat to travel downstream?.
