What is the difference between distance and displacement?

a
Distance is measured in feet. Displacement is measured in meters
b
Distance is the length of travel. Displacement is the straight line distance between the starting point and the ending point
c
Distance is the difference between how quickly you move between two points. Displacement is the average of that motion
d
Distance is a measure of length of travel. Displacement is the measure of the time it takes to move that length

b

Distance is the length of travel, measured in any units (feet, meters, kilometers, etc.). Displacement, on the other hand, is the straight line distance between the starting point and the ending point, measured in the same units as distance. Displacement takes into account both the distance traveled and the direction of travel.
