Best ResponseYou've already chosen the best response.0I know how to solve it in neat. All I want is the trick!! :) Here is my logic let x is the speed of the boat y is the speed of the water then the speed of downstream is x +y upstream is xy Let D is distance of the stream, hence \(\dfrac{D}{x+y}+\dfrac{D}{xy}=6\\\dfrac{2D}{x+y}=4\) Solve the system. we can get the answer.
