From school, Paolo walks 5 km south, turns right and walks 4 km, then turns right again and walks 8 km. In which direction is he from the school?
Correct answer: C. Northwest
Facing south, a right turn faces west, and another right turn faces north. Net movement: 4 km west and 8 − 5 = 3 km north. He is to the northwest of the school, 5 km away.
