### 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

$={\displaystyle \frac{1}{2}}(a+b)$ km/hr

Rate of stream =

km/hr
