( About 45 seconds, in my case. Sorry, z-chan. I don't enjoy doing this sort of math, especially first thing in the morning, but since it was a riddle I thought I'd look it over to see where the "trick" was. Oddly enough, to me it didn't look like a riddle at all, just bad math. I'm far to literally-minded about these things.  ) |
