A man takes twice as long to row a distance against the stream as to row the same distance in favor of the stream . The ratio of the speed of the boat (in still water ) and the stream is : Correct Answer 3: 1

Let , Distance = x we know, Down stream = Boat + Stream Up stream = Boat - stream ATQ, 2xBoat  + stream  = xBoat  - Stream⇒2x (Boat  - Stream) = x(Boat  + Stream ) ⇒2Boat  - 2 Stream  = Boat  + Stream ⇒2 Boat  - Boat  = 2 Bstream  + Stream⇒Boat  =  3 Stream ⇒BoatStream  = 3.'.Boat : Stream  =  3 : 1
