Question

Tina starts her paper route at the corner of two streets. She travels 8 blocks south, 13 blocks west, 8 blocks north, and 6 blocks east. How far is she from her starting point when she finishes her route?

Answer 1

if the starting point is (0,0), then she goes to (0, -8), then to (-13, -8), then to (-13, 0), then to (-7, 0).  (-7, 0) is 7 units from the starting point. So, 7 blocks.
