WebFormulas for Upstream and Downstream Problems Below are the important formulas for the various boats and streams concepts. To calculate, Upstream = (u−v) km/hr Boat’s speed in still water = ½ (Downstream Speed + Upstream Speed) Downstream = (u+v)Km/hr Boat’s average speed = { (Upstream Speed x Upstream Speed)/Boat’s Speed in Still Water} WebTime upstream = Time downstream Now, speed, or velocity, is distance divided by time -- so many miles per hour: Therefore, t = d v The equation will be Problem 5. The speed of a boat in still water is 15 mi/hr. If the boat travels 8 miles downstream in the same time it takes to travel 4 miles upstream, what is the speed of the current?
Upstream: Key concepts from Dan Heath
WebProblem 4 : A boat covers 24 miles upstream and 36 miles downstream in 6 hours while it covers 36 miles upstream and 24 miles down stream in 6.5 hours. Find the speed of the stream. Solution : Let x and y be speed upstream and downstream respectively. The formula to find the time : time = distance/speed. We can use the above formula and find ... WebA boat takes 2.5hr to go 20mi upstream against the current. It can go 40mi downstream with the current in the same amount of time. Find the speed of the current and the speed of the boat in still water. Question: A boat takes 2.5hr to go 20mi upstream against the current. It can go 40mi downstream with the current in the same amount of time. rcvs personal growth
