Which car is the cheapest to run?Explain why.

Bill's car: average fuel composition 20 miles per gallon

Sue's car: average fuel composition 30 miles per gallon

Fred's car: average fuel composition 40 miles per gallon

I think the answer is Fred because his car can travel 40 miles per gallon.

sorry composition is actually supposed to be consumption

Your answer is correct. Fred's car is the cheapest to run among the three options. Let me explain why.

To determine which car is the cheapest to run, we can consider the fuel efficiency of each car. Fuel efficiency is usually measured in miles per gallon (MPG).

Bill's car has an average fuel consumption of 20 miles per gallon. This means that for every gallon of fuel used, the car can travel 20 miles.

Sue's car has a better fuel efficiency than Bill's. It can travel an average of 30 miles per gallon, meaning it requires less fuel to cover the same distance as Bill's car.

Fred's car, on the other hand, has an even higher fuel efficiency compared to Bill and Sue. It can cover 40 miles on a single gallon of fuel, which is significantly more efficient than both Bill's and Sue's cars.

Therefore, since Fred's car has the highest mileage per gallon, it requires the least amount of fuel to cover the same distance as the other cars. This makes it the cheapest to run in terms of fuel consumption.
