a company wants to test the effectiveness of a new ethanol based fuel. they fill a kia soul completely with standard gasoline. with the old fuel in the car, they drive at 20 mph until they run out of gas. they measure how many miles they are able to drive without filling up. they then fill the kia soul with the new ethanol based fuel and repeat the process.
independent variable
dependent variable
constant
control variable

Explanation:

In an experiment, the dependent variable is what is measured and depends on the independent variable (here, fuel type). The distance driven is measured to see how it's affected by the fuel (standard vs. ethanol - based). So it's the dependent variable. The initially selected "Independent variable" is incorrect as the independent variable is the fuel type.

Answer:

B. Dependent variable
