Question

distance is to displacement as —.
o centimeters is to meters
o a vector is to a scalar
o speed is to velocity
o distance is to time

Explanation:

Distance is a scalar quantity (only magnitude), displacement is a vector quantity (magnitude and direction). Speed is a scalar (only magnitude), velocity is a vector (magnitude and direction). Centimeters and meters are units (same - type quantity, scalar). A vector to a scalar is the reverse of the required relationship (distance - scalar, displacement - vector). Distance and time are different physical quantities with no such scalar - vector relationship as distance - displacement.

Answer:

speed is to velocity
