17 Blocks altogether
You would have to walk 10 blocks south and then 5 blocks west or something like that for example 3 blocks west then 5 blocks south then 2 blocks west then 5 blocks south again but it all adds up to be a total of 15 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 !

11 blocks: 1 more W and 10 S
To complete the circle you would have to walk 10 blocks south and 1 block east to return to your starting point, 11 blocks.
2 blocks west and then 3 blocks south
3 blocks west
This would take approximately 6.5783 days, walking non stop. This is assuming you are walking from north to south. If you were walking from East to West, the time would vary vastly.
Using X and Y as the map coordinates, where X is east and west (positive or negative) and Y is north and south (positive and negative), and the point 0,0 as a starting point, you can show the following: * 14 blocks north to 0,14 * 16 blocks east to 16, 14 * 26 blocks south to 16, -12 The final location is 12 blocks south and 16 blocks east of the starting point. If there were a straight diagonal street, the truck would be 20 blocks from the start (square root of 122 and 162), just east of a SE direction.
You couldn't walk from Middlesbrough to South Africa. You would have to travel by plane which would take 11 hours, 53 minutes.
