Feb. 11, 2009 Graph the following scenario: I walked 9 blocks to the coffee store in 8 min. Then, I sat at the store for 10 min. I walked 4 blocks back toward my starting point in 4 min before realizing I had left something at the coffee shop. I immediately turned around and walked 4 blocks back to the coffee shop in 6 min and was there for 2 min. I walked the 9 blocks back to my starting point in 10 min.
