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...

I think in other posts I've stated my support of time-money as the driving unit of value.

So your commute costs you:
t(v) = 20 * Distance / v
g(v) = Av + Bv^2

and we want to minimize t(v) + g(v). Fun. :)

Do you have any fuel efficiency stats for your car so we can solve for constants A and B?

In response to your icon, the math department at neu had this fun solution:

1/n * sin x = 1/n * sinx = 1 * six = 1 * 6 = 6!

We're doing imaginary numbers in math. I might need your help when we get our graded assignments....

Topology was sweet, though. And the 4 question assignment only took me two and a half hours!....only 2 of us actually completed the problems! Hooray!
