Answer: The rate of change represents number of miles traveled for every 1 gallon of gas used.
Step-by-step explanation:
A rate of change is a rate that illustrates how dependent variable changes in relation to independent variable.
Here the independent variable is "gas used in gallons".
and the dependent variable is "distance traveled in miles"
Thus the rate of change =[tex]\frac{\text{change in distance}}{\text{change in amount of gas}}[/tex]
Thus, It illustrates number of miles traveled for every 1 gallon of gas used.
Hence, The rate of change represents number of miles traveled for every 1 gallon of gas used.
