One of my favorites is just a step above the standard 'walk on the shore, swim through the water' problem. Why I like it so much is that one of my students (a few years ago, as you can tell from the dates) showed the problem to his father who said, "We just did that project at work!" It's from a book Joe Fiedler and I did a while ago, "Calculus Projects with Maple;" we called it the "Otsego Electric Company." Look at http://www.mathsci.appstate.edu/~wmcb/Class/Projects/OEC/ for the description.
