### Instruction: Arthur walks six blocks east and then 12 blocks north. If each block is one-third of a mile, how many miles did he walk?### Response: To find the total distance Arthur walked, I need to add the distances he walked east and north.
The distance he walked east is six blocks times one-third of a mile per block, which is two miles.
The distance he walked north is 12 blocks times one-third of a mile per block, which is four miles.
