# tricky math problem

Posted on 2011-04-26

The original question and the work I did on it is attached (the work I did is a bit short-cut since I've verified my answer until that point).

My problem is with part B, when I solve for it, I get x = 4/3, which would technically make this traveler travel a bit further than needed to get to the destination, which would make no sense, unless he just really loves to row/walk...

Any guidance on the matter?

And to the mods and experts who will be complaining about providing direct solutions, this is no different than me posting C++ code and having other experts rip it apart and show me better ways of doing the same thing, which does not violate any rules.
