Avery's adventurous dog, Max, decided to explore the neighborhood! First, Max trotted 40 m to the west to chase a butterfly, then darted 10 m back to the east when he heard Sophia calling, and finally, he sprinted 50 m south to catch up with Mia at the park. Can you calculate the total distance Max traveled and his overall displacement? ( make sure to draw it out to understand Max's motion)
distance = 100 m, displacement = 58 m SW
