Quizplus · Accepted Answer

Let x be the miles driven in the city and (300 - x) be the miles driven on the highway. The total gasoline used for both city and highway driving is 15.5 gallons. The equation can be set up as x/18 + (300-x)/21 = 15.5. Solving this equation for x gives the miles driven in the city as 153 miles.
