5. (8 points) Use the graph below to sketch Marie's drive to work. Distance from home (in miles) should be the label on the vertical axis and time from home (in minutes) should be the label on the horizontal axis. 0 It takes Marie 40 minutes to drive the 20 miles it takes her to get to work each day. On a recent drive to work, she realizes 5 minutes in that she forgot her briefcase at home and had to return to get it. She nds a convenient place to turn around 5 miles into her drive and heads back home. Her speed up to the 5 mile turn around point and her return trip home are the same. After getting her briefcase, her trip to work is slowed by the steady trafc on the road. She realizes that it has taken her 17 minutes to nally reach the railroad tracks which are 12 miles from home. As she approaches, the cross arms go down signaling there is a train approaching. She must stop and wait for the train to pass which takes 10 minutes. She looks at her watch and realizes that she will be late to work if she doesn't speed a bit. Marie drives faster than the posted speed limit for the remainder of her commute and is not late for work
