To find out how many gallons of gasoline you would need to travel 297 miles at the same rate, you can use proportions.
First, calculate the rate of fuel consumption by dividing the distance traveled by the amount of gasoline used: 189 miles / 7 gallons = 27 miles per gallon.
Next, use this rate to determine the number of gallons needed to travel 297 miles:
297 miles / (27 miles per gallon) = 11 gallons.
So, you would need 11 gallons of gasoline to travel 297 miles.
Therefore, the correct answer is:
A) 11 gallons.
