The cross-country team goes on a 10-mile run after school. They end the run outside of the locker room, where they started. Find the distance and displacement of the runners.

• distance = 10 miles

  displacement = 0 miles

• distance = 10 miles

  displacement = 10 miles

• distance = 20 miles

  displacement = 0 miles

• distance = 20 miles

  displacement = 20 miles

A family travels 110 km east to spend the night in a hotel. The next day they drive back home, but after travelling 45 km west they decide to stop and visit with friends for the night. Find the distance and displacement of the family.

• distance = 155 km

  displacement = 65 km W

• distance = 110 km

  displacement = 65 km

• distance = 155 km

  displacement = 118.8 km W

• distance = 110 km

  displacement = 118.8 km W
