When you select (highlight) with mouse distance to drive (ex: "490 mi" or "490"), the Miles Per Dollar Calculator add-on will calculates price for gas and show it in the popup message. You specify average MPG of your car (ex: 30) and average gas price (ex: 3.99) in Preferences.
You can get MPG at http://www.fueleconomy.gov/feg/findacar.htm
and your local gas prices here: http://gasbuddy.com/
DISCLAIMER: this is just an estimate price! YMMV!!!
