Answer: Distance = 15km ; Displacement ≅ 11'2km

Explanation:

In Physics when we speak of distance we refer to the space traveled that is always measured on the trajectory, while displacement refers to the space from an initial position to a final position regardless of the path. When the path is a straight line, the space traveled is equal to the module of the displacement.

Distance: 5km + 5km + 5km = 15km (Red lines)

Displacement² : (10km)² + (5km)² = 100km² + 25km² = 125km²

Displacement : √125km² ≅ 11'2km (Blue line)
