Being a boat sailor, Shyam moves downstream at speed = 12 + 6 = 18 km/hr & upstream at speed = 12 � 6 = 6 km/hr Therefore, average speed of boat sailor = Downstream speed x Upstream speed . Explanation. Downstream Speed = 30/2 = 15 km/hr Upstream Speed = 30/6 = 5 km/hr Speed of the boat in still water = 1/2* (downstream speed + upstream speed) = 1/2* (15+5) = 10 km/hr. Q 10 - A steamer goes downstream from one point to the other in 4 hrs. It Speed Of The Boat In Upstream Upgrade covers the same distance upstream . 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.
Main point:
