Draw the story of the graph.
Lucy drives to work which is 35 miles away from her house. She travels at 65 miles per hour and
arrives at her job in 1 hour. She works for 5 hours before she is allowed to go home. Then Lucy leaves
her job and decides to stop for food on her way home. She stops at a fast food location which is only
10 miles way from her job and 25 miles away from her home. It took her an hour to arrive at the fast
food location and 1 hour to get her food. Finally Lucy leaves the fast food location and drives home.
Traffic is terrible and it takes Lucy 3 hours to travel from the fast food location back to her house.
