<h2>Answer:</h2>

The blue car has traveled the greater distance on one gallon of gasoline
<h2>Explanation:</h2>
The formula for calculating the unit rate is expressed as shown:

For the blue car
Distance = 39.5miles
Gallons of gasoline = 1.25 gallons
Get the unit rate:

The unit rate of the blue car as a mixed fraction is 31 3/5 miles per gallon
For the red car
Distance traveled = 22.4 miles
Gallons of gasoline = 0.8 gallons of gasoline
Get the unit rate of the red car;

From the unit rates, we can see that the blue car has traveled the greater distance on one gallon of gasoline since its unit rate is greater than that of the red car.
Answer:You can determine whether each element of the domain is paired with exactly one element of the range. For example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
