Beth leaves her house to drive to work. She first travels 9 miles west and 9 miles north before stopping to put
gas in her car. She then travels 6 miles west and 6 miles north before stopping to pick up a coworker. From the
coworker's home, they then travel 10 miles east and 7 miles south to their office. Overall, how far east/west and
north/south is Beth’s office from her home? What displacement is her office from her home?
