A chihuahua gets loose from his yard and goes for a run in the neighborhood. He first runs 4 blocks east, then he got chased off by a schnauzer and had to run 4 blocks north. Then he got scared by a cat and ran 6 blocks south until he smelled someone cooking food outside and followed the smell 2 blocks east. They chase him off and he runs 3 blocks south and 3 blocks west. Then he wanders 2 blocks north looking for trees and fire hydrants. Where is he? What is his displacement?
