GIVEN:

If the EPA rating for a car is 22 mpg.

Required;

To calculate the amount of fuel needed for a 763-mile trip.

Step-by-step solution;

At the rate of 22 miles per gallon, a one-mile trip would require;


\begin{gathered} 22\text{ }miles=1\text{ }gallon \\ \\ 1\text{ }mile=(1)/(22)\text{ }gallons \end{gathered}

Hence, for a 763-mile trip, the amount of fuel needed will be;


\begin{gathered} 763\text{ }miles=((1)/(22)*763)\text{ }gallons \\ \\ 763\text{ }miles=34.6818181818\text{ }gallons \end{gathered}

Rounded up to the nearest whole number we now have;

ANSWER:

763 miles would require about 35 gallons of fuel
