(Those questions always make me nervous. What if I can't actually do the problem? Then I look dumb.)
The section of the run that he's most worried about is from miles 5.5-ish to 8, which climbs about 280 feet. Our question was how do we convert that to a percentage at which he can set his treadmill?
My friend and I sat and figured it out last night (after I discovered that a 45 degree angle is considered a 100% incline... which doesn't make sense to me, but whatever).
And what a perfect question to open with in today's precalc class! Yes, they think I'm a geek for sitting and doing math with my friends, but after I convinced them that this was a legit problem that we were trying to figure out, most kids bought in.
(Want an answer? Figure it out for yourself :) )
