Re: Is this word problem solvable?

d1 = 2 miles + (v-s)(1 hour) = 2 + v - s

Where did the units go here? Canoeist travels upstream 2 miles and encounters log, an hour later he turns around. How does the distance before the log correlate to the time after the log? Unless we read "after *another* hour" to mean that the first 2 miles took an hour, I don't see how this is solvable.

The formula is the same as I came up with but the idea of the stream speed being relative was the missing link. Thanks for the in depth discussion/explanation. Probably would have been much easier if I knew no math at all. [img]/images/graemlins/grin.gif[/img]
