700 nautical miles is more in the ballpark. See below.

My 320 carries 43 gal of fuel. It burns 8 gal/hr.
Taking off 6 gal for 45 minutes reserve at normal cruse power leaves 37 gal.
An alternate .6 hours away would be 180 kts * .6 = 108 nautical miles
and use .6 hours * 8 gal/hr = 4.8 gal.
Take this away and get 37 - 4.8 = 32.2 gal.
32.2 gal / 8 gal/hr * 180 kts = 724.5 nautical miles.
If headwinds are forecast (or found in flight) a closer airport will
need to be found for refueling.
I have flown my 320 over 800 VFR nautical miles several times. When
both of my wings are dry, I start getting nervous and find an airport.
Did you know that the U.S. contains about 12,000 airports? How far
apart are they?
1,000 * 2,000 = 2,000,000 sq mls
2,000,000 sq mls / 12,000 = 167 sq mls per apt
square root( 167 ) = 13 mls
Therefore there is an airport approximately every 13 mls in the United States.
