I went down t...Quite the elegant solution, Blaine. I went down the Happy Steve road as well and then, seeing my nasty equations (and, literally out of back of the envelope space), put it all off for later (which became actually never). I guess the real ah ha moment is when you figured that each couple's second day travel is equivalent to the other's first day. I knew that as I drew my figure and set up my equations but I never used it to my advantage. Big time saver that and much simpler equations to boot.gregdavidhttps://www.blogger.com/profile/13511045845739028402noreply@blogger.comtag:blogger.com,1999:blog-5730391.post-15656359916786118772008-07-25T10:02:00.000-07:002008-07-25T10:02:00.000-07:00wow, that is a LOT cleaner than what I did (and I ...wow, that is a LOT cleaner than what I did (and I suspect ralph loizzo also did also), which was figure out the distance of the two paths first. It involved a huge trinomial which I had to plug into the quadratic equation. Of course it resulted in the same answer, the shorter path = 360 miles, longer path = 480 miles, thus the whole road is 840 miles.Happy Stevehttps://www.blogger.com/profile/04548800864932721392noreply@blogger.com
