Question

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

Answer 1

Let speed of man upstream= x kmph & his speed downstream = 2x kmph

Hence the ratio will be , (2x+x)/2 : (2x-x)/2

                                       3x/2 : x/2

                                        ⇒3:1
