• If the speed of a boat in still water is u km / hr and the speed of the stream are v km / hr then
• The formula for speed downstream is (u + v) km / hr
• The formula for speed upstream is (u – v) km / hr
• If the speed downstream is a km / hr and the speed upstream is b km / hr then,
• Speed in still water = ½ (a + b) km / hr
• Rate of stream = ½ (a – b) km / hr
