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 :

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
