A college student named Nova walked 500 meters for 500 seconds from her dormitory building to find her
favorite bench in a park. She called her mom and talked for 100 seconds at the bench, but suddenly she
remembered that she did not turn off the gas stove. So, she returned her dorm by running for 100
seconds. To find out Nova's average velocity for each case while walking, resting, and running, begin by:
plotting a graph between position and time.
