If you plot this on a coordinate plane starting at (0,0) you see it ends up at the point (-3,-4). Use the distance formula between the two points. The distance formula is the squareroot of the difference between the x's squared plus the distance between the y's squared.


sqrt%28%280%2B+-3%29%5E2+%2B+%280+%2B+-4%29%5E2%29+=+sqrt%289%2B16%29+=+sqrt%2825%29+=+5. The distance is 5 miles.
