Answer:
Distances: BC = 20, CD = 40, BD = 20
Displacement: insufficient information
Explanation:
Distance is the (positive) difference between the right-end coordinate and the left-end coordinate:
B to C = 35 -15 = 20
C to D = 35 -(-5) = 40
B to D = 15 -(-5) = 20
__
The displacement cannot be figured unless starting and ending positions are named.
