Draw a graph that pictures each situation. Explain any assumptions that you make. Identify the independent and dependent variables. Determine the intervals on which the dependent variable is increasing, decreasing, or constant. Answers may vary.

Captain Janeway left the holodeck at 7:45 to meet Tuvok, her chief of security, on the Bridge. After walking for 3 minutes, she realized she had forgotten her tricorder and returned to get it. She picked up the tricorder and resumed her walk, arriving on the Bridge at 8:00. After 15 minutes the discussion was over, and Janeway returned to the holodeck. Graph Janeway's distance from the holodeck as a function of time.
