2. Kevin drives to the pizza place for lunch. He walks 5 km east, then 5 km south, then 5
km east again.
Distance:
Displacement:

Distance = 15km ; Displacement ≅ 11'2km

Step-by-step 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)

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175
