The explanation and answer are below.

Work Step by Step

If a variable is dependent on another variable, it means that the variable changes based on what value the other variable has. For instance, consider two variables: time in a race and how far a runner has gone. Time in a race is not dependent; no matter where the runner is, time continues to go forward. However, because it takes the runner time to go somewhere, the runner's location depends on how far into the race we are. Thus, we call the runner's location the dependent variable.
