Is the number of miles driven proportional related to the number of gallons of gas consumed?

Yes, the number of miles driven is generally proportional to the number of gallons of gas consumed, assuming a consistent fuel efficiency. This relationship can be expressed with the formula: miles driven = fuel efficiency (miles per gallon) × gallons of gas consumed. However, this proportionality holds true under normal driving conditions and may vary with factors like driving habits, vehicle condition, and road conditions.
