Final answer:
Without the specific weight and MPG values of the car, it's impossible to determine if its MPG is above or below average. Generally, cars are becoming more fuel efficient, and the efficiency for vehicles varies based on a range of factors, not just weight. Airplanes may use more fuel but can be more efficient on a per-passenger basis.
Step-by-step explanation:
When assessing whether a car's miles per gallon (MPG) is above or below average, it's crucial to collect data on fuel efficiency related to the car's weight. To compare fuel efficiency, you will need actual values for the car's weight and MPG which were not provided in the question. However, airplanes are known to get less than one mile per gallon, though when considering the number of passengers, this can be more efficient on a per-passenger basis — around 90 MPG per passenger. If a car can beat this fuel efficiency, it would be considered very good.
To evaluate whether a car's MPG is above or below average, we can look at data for 30 cars and see their MPG range from 19 to 43. An average can be calculated, and individual car MPG can be compared to determine its standing.
Fuel efficiency does not solely depend on the car's weight; factors such as aerodynamics, engine efficiency, and driving conditions also play roles. However, generally, as cars are becoming more fuel efficient, a higher MPG is expected from modern vehicles.
