Given: Table showing how the number of training miles run ny a runner affects her time to finish the race.
Required: Identify the dependent variable and independent variable.
Step-by-step explanation:
As we can see, as the number of training miles (x) increases, the runner takes lesser time to finish the race(y).
As x increases, y decreases. So, y is dependent upon x.
Hence, x is independent variable as she can do training for as many hours she wants, and this will affect the y, which is a dependent variable.
Final answer:
Dependent variable: Time to finish the race.
Independent variable: Number of training miles.
