Optimizing my commute III

[asterroc]

I was reminded by mathsex people that (1) if I assume gas mileage and speed are equally important, that I could just average the optimal speed for both and I get around 65mph for the ideal driving speed, or (2) a potential way of giving a more realistic value to my time as compared to the gas mileage is to put a dollar value on my time - according to my salary that's around $20/hr. More math to come...

Doesn't 0!=0 ?

0! is defined to equal 1 to satisfy a bunch of other math things. One way to think about it in the real world is, with 3!, you have 3!=6 ways to permutate 3 objects. You have 0!=1 way to permutate "no" objects. It's silly, but that's the way I've always thought about it. My way of permutating no objects is the same way that anyone else can do it. (:
