In fact, in some anthropological studies hunter gatherers that don't know arithmetic mostly said that the value halfway between one and nine is three.
Which still doesn't produce the right answer; you save three times as much gas going from 10MPG to 30 compared to going from 30 to 90. (More generally, going from k to kn MPG saves n times as much as going from kn to k*n^2).
- ta12121 14y agoI don't think the emphasis on saving is correct. You're picking an arbitrary origin which is not zero. If you go from 10 MPG to 30 MPG you are now using 1/3 as much gas. If you go from 30 MPG to 90 MPG you are once again using 1/3 as much gas.
