Final answer:
To rank vehicles based on fuel consumption, consider their miles-per-gallon ratings in reverse order; a lower MPG indicates higher fuel consumption. A car with 19 MPG consumes the most fuel, whereas one with 43 MPG is the most fuel efficient.
Step-by-step explanation:
Understanding Fuel Consumption Ranking
To rank the vehicles from greatest to lowest fuel consumption, we need to inversely relate this to their miles-per-gallon (MPG) ratings. As fuel efficiency increases, fuel consumption drops. Thus, a car with a lower MPG rating consumes more fuel compared to a car with a higher MPG rating. Let's take four random vehicles from the provided list with MPG ratings of 19, 25, 37, and 43.
Vehicle with 19 MPG (highest fuel consumption).
Vehicle with 25 MPG.
Vehicle with 37 MPG.
Vehicle with 43 MPG (lowest fuel consumption).
The car with 19 MPG rating consumes the most fuel as it travels fewer miles per gallon of fuel. Conversely, the car with 43 MPG is the most fuel efficient as it travels the most miles per gallon. This efficiency is crucial for manufacturers to meet fuel economy standards, such as the one announced by President Obama for an average of 35.5 MPG by 2016.
