Hello all, I am a student of high school and found an interesting question, but I do not know resolve. I'm from Brazil, sorry for the mistakes in English. I believe that to understand one must understand the question before, so I'll have to post the two here: 2) Where a traveler will come if he keeps always walking to: a) North b) South c) east d) West 3) Where it will come if you keep walking in a southwesterly direction? How many miles he has walked to the end point? How many rounds he will have made around this point? Thank you for your attention.
