You can put this solution on YOUR website! A man walks 5 miles North, 3 miles West, 8 miles South, and 7 miles East. What is his distance from his starting point?
-----
Starting at (x,y) = (0,0)
---
Change in "x" values:: 3 West then 7 East ends at x = 4
Change in "y" values:: 5 North then 8 South ends at y = -3
Ending at (4,-3)
----
Distance: = sqrt[4^2+3^2] = sqrt(25) = 5
