Answer:
Cuando voy a pie al supermercado, me canso mucho.
- on foot
Step-by-step explanation:
Assuming the underlines word/phrase is a pie, the equivalent English word would be "on foot". "A pie" means someone or something walking from one location to another. In this case, the person is walking from someplace to the supermarket- "al supermercado" and they become very tired when they walk to the supermarket- "me canso mucho".
