Which is the dependent variable in the following situation?:

A marine biologist wants to track the miles that a particular dolphin travels over the course of a year. The tracking system records the distance each week.

A. length of dolphin. B. number of dolphins C. weeks of tracking. D.miles traveled

I would use time as the independent variable (weeks) and distance as the dependent variable.
