Henry rides a boat for a fishing trip at 6 meters South. After 1 hour of waiting no fishes were caught, so he goes 4 meters west. Then he follows a school of fish 2 meters South. How long did he travel? Is the boats’ displacement equal to zero? What is his displacement?

Back

12 meters; 12 meters south

Front

Back

distance = 12 m, displ = 9 m
