You did not give the variables or numbers. This question would be a uniform rates problem for the rate as fuel efficiency. It could be done completely in symbols, but better that you indicate what is known and what is unknown, and use either values or variables, or both.

Basic idea to use would be Rv=d, R for fuel efficiency, v for gallons of fuel, d for miles traveled.

Your description indicates two totals: one for fuel and one for miles distances. You would likely obtain two equations in two unknowns.
