Final answer:
The car that travels the farthest on 1 gallon of gas out of the given list is the one with the highest miles per gallon rating, which is 43 miles per gallon.
Step-by-step explanation:
The question requires us to determine which car has the highest miles per gallon (mpg) rating out of a list provided.
To find which car travels the farthest on 1 gallon of gas, we look for the highest number in the provided mpg ratings list. The list in ascending order is: 19, 19, 19, 20, 21, 21, 25, 25, 25, 26, 26, 28, 29, 31, 31, 32, 32, 33, 34, 35, 36, 37, 37, 38, 38, 38, 38, 41, 43, 43.
From this list, the highest number is 43 miles per gallon, which indicates the cars with this rating are the most fuel-efficient and travel the farthest on 1 gallon of gas
