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:

Question

Accepted Answer

Let man's rate upstream be x kmph. Then, his rate downstream = 2x kmph. ∴ (Speed in still water) : (Speed of stream) =

∴ (Speed in still water) : (Speed of stream) =	❨	2x + x	❩	:	❨	2x - x	❩
		2				2
