Jun 12, �� Average Speed of Boat = {(Upstream Speed ? Downstream Speed) / Boat�s Speed in Stii Water} If it takes �t� hours for a boat to reach a point in still water and comes back to the same point then, the distance between the two points can be calculated by Distance = {(u 2 -v 2) ? t} / 2u, where �u� is the speed of the boat in still Estimated Reading Time: 4 mins. A boat covers 14 kms in upstream and 20 kms downstream in 7 hours. Also it covers 22 kms upstream and 34 kms downstream in 10 hours. Find the speed of the boat in
The Speed Of The Boat Upstream Effects still water and of that the stream. Sep 26, �� The speed of the boat is given by = 1/2 (downstream speed + upstream speed) The speed of the stream is provided by = 1/2 (downstream speed � upstream speed) A certain distance in p1 hours is covered by a man when he rows downstream and comes back the equal distance upstream in p2 hours. If the stream�s speed is assumed as s km/hr, then the man�s speed in still water will be: s .
