## Important Formulas of Boats and Streams

1. Boat going Downstream:

If boat is going in the direction of water flow then it is called boat going downstream.2. Boat going Upstream:

If boat is going opposite to the direction of water flow then it is called boat going upstream.3. Speed Downstream: If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then:

Speed downstream = (u + v) km/hr.

Means the speed of stream and of boat will be added.4. Speed Upstream: If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then:

Speed upstream = (u – v) km/hr.5. If the speed downstream of boat is a km/hr and the speed upstream of boat is b km/hr, then

Speed in still water =1/2 (a+b)km/hrSpeed of stream =1/2 (a−b)km/hr
