Edward and his family are sightseeing. They walk two blocks north, four blocks west and two blocks south. All together they have walked blocks and have a total displacement magnitude only of 8. 2+4+2=8
You finish 2 blocks east and 8 blocks south of your starting point.
11 blocks: 1 more W and 10 S
8 R1CO95- Well eight not 8. ^_^
To complete the circle you would have to walk 10 blocks south and 1 block east to return to your starting point, 11 blocks.
It's a total of seven blocks... You would need to walk 5 blocks south, and 2 blocks east to end at your original starting place !
