Efficiency of machines quick check which car has the greatest efficiency

In order to determine which car has the greatest efficiency, we need to calculate the efficiency of each car. Efficiency is typically calculated as output divided by input.

For example, if Car A uses 10 gallons of gas to travel 300 miles, and Car B uses 12 gallons of gas to travel the same distance, we can calculate the efficiency of each car by dividing the distance traveled by the amount of gas used.

Car A: 300 miles / 10 gallons = 30 miles per gallon
Car B: 300 miles / 12 gallons = 25 miles per gallon

Based on these calculations, Car A has the greatest efficiency with 30 miles per gallon compared to Car B's 25 miles per gallon.
