Miles per dollar Tue, Sep 27, 2011
Not to beat a dead horse, but I was thinking recently that a helpful way to understand how far a dollar will allow you to travel is to calculate miles per dollar, which is just gas mileage divided by the price of a gallon of gas.  So if my car gets 30 miles per gallon and gas costs $3.00 per gallon, that means a dollar will get me 10 miles.  This is helpful if, for example, you're really low on gas and need to figure out if the spare change under your seat can get you home. #travel
