True.
13. A person walks 2 miles north and then turns around and walks 3 miles south. Total time elapsed = 1 hour.

1. Distance (d) =

2. Displacement (Δx) =

3. Average Velocity (⊽) =

4. Average Speed (s) =
1. d = 2 + 3 = 5 miles

2. Δx = 2 miles (N) - 3 miles (S) = 1 mile (S)

3. ⊽ = Δx/Δt = 1 miles/1 hour = 1 mile/hr (S)
