Highway travel: 1000 miles.  Therefore, city travel = 1250 - 1000 = 250 miles.
30 miles on highway requires 1 gallon
Therefore, 1000 miles on highway will require how many gallons?

30 miles in city requires 1 gallon
Therefore, 250 miles in city will require how many gallons?

Add them up for the total gallons.
