For the equasion to be correct the gallons used for each fill must be included, or you can use total miles and total gallons combined.

10 gallons 1300 miles @130 MPG
10 gallons 700 miles @ 70 MPG

2000 miles and 20 gallons is 100 MPG.

Am I missing something?

edit, oops sorry red devil already covered it, long day today.
