Boat and Stream Formula

Downstream: In water, the direction along the stream is called downstream.

Upstream: In water, the direction against the stream is called upstream.

Let the speed of a boat in still water be u km/hr and the speed of the stream be v km/hr, then

Speed downstream = (u + v) km/hr
Speed upstream = (u - v) km/hr

Let the speed downstream be a km/hr and the speed upstream be b km/hr, then
Speed in still water

Speed in still water $=\frac{1}{2}(a+b)$ km/hr
        Rate of stream = $\frac{1}{2}(a-b)$ km/hr
