Distance traveled N/S:
(80 m north) + (20 m south) + (60 m south)
(80 m) + (-20 m) + (-60 m)
0 m north/south
Distance traveled E/W:
(15 m east) + (35 m west)
(15 m) + (-35 m)
-20 m
20 m west
Resultant distance:
a² + b² = c²
a = 0 m north/south
b = 20 m west
c² = (0 m)² + (20 m)²
c² = (20 m)²
c = 20 m
Overall displacement = 20 m
