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

Hello friend

In both the cases of going in favour and against the stream the distance is the same

The time in going against the stream is twice the time taken to go in favour of the stream

Let the time taken to go in favour of the stream be x

Time taken to row against the stream be 2x

Speed in still water distance/time = y/x

Speed in rowing against the stream = y/2x

Ratio y/x : y/2x

=1:1/2

=1:0.5

Hope it helps!
