Jill sets out from her home to deliver flyers for her yard sale, traveling due east (+x) along her street lined with houses. After going 500 m she runs out of flyers and has to retrace her steps back to her house to get more. After picking up more flyers, she sets out again on the same path, continuing where she left off, and ends up 1000 m from her house. At this point she turns back toward her house, heading west (-x). After 1750 m she stops to get ice cream (Draw pictures to help with your calculations.) What is Jill’s total displacement to the point where she stops to get ice cream? What is Jill’s total distance traveled? please show work.. thank you
