A woman walks 3 blocks north to her office. During her lunch hour, she walks 6 blocks east to a restaurant and then returns to the office. After work, she travels 1 block north and 4 blocks west to her brother's apartment for dinner.
(1) What is the total distance traveled by the woman during the day?
Total distance covered includes all of her walking trip. 3+6+6+1+4=20 blocks. Note that units must be included.
(2) What is her net change of position? Assume that total walking time for the day was 20 minutes.
No net distance was traveled during the trip to the restaurant at lunch, so the net change of position is 4 blocks north and 4 blocks west, or 5.66 blocks at 45 degrees north of west.
