Create a Graph to represent the following situation using total distance with respect to time.  Karl arrived at the mall at 10am. He spent 2 minutes waiting at the entrance for his friend Steve. The boys walk at a constant speed of 100ft/min all day. They spent 6 minutes walking to the Pet store and then stopped to look at the puppies in the window for 5 minutes. After the pet store, it took them 3 minutes to walk to the food court where they stopped and got a drink for 4 minutes. After they finished their drink they moved in the direction of the sports store for 7 minutes.
