A. Sketch the path that Sarah takes as she does these errands on the map above.
 Sara starts from her house, which is house D.
 She leaves the house through the front door shown on the map and goes
100 m west and 10 m north to the Computer Store.
 After purchasing a new mouse for her computer, Sarah walks 800 m east
and 400 m north to the Post Office to mail several letters.
 From there she walks 1200 m west to visit a sick friend in the hospital.
