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...

Reminds me of one a math teacher told me. He taught them how

Lim(x->0) of (8/x) = ∞

And on an exam he gave

Lim(x->0) of (5/x) =

to which the student replied with a sideways 5.

*snort*

I have to say that I would also have been tempted to answer that question that way.

On a slightly related note, I just today realized that one can interpret your icon as "no, you idiot, x is over here by the 0 symbolizing the number of points you're about to get". :) (Yes, I know that's not what the red 'x' symbolizes. But it tickles me that you can read it that way.)

Every time I see it I think x₀ as in "initial x position."

*nods* I can see that. Although it looks a bit more like X₀, i.e., perhaps the first in a series of state variables X or something, rather than a lower-case x. To me, anyway.

So many silly willful misinterpretations, so little paper on which to write them...
