distractor3: reason

correct_answer: direction
support: When both distance and direction are considered, motion can be represented by a vector. A vector is a measurement that has both size and direction. It may be represented by an arrow. If you are representing motion with an arrow, the length of the arrow represents distance, and the way the arrow points represents direction. The red arrows on the map in the Figure above are vectors for Jordan’s route from his house to the school and from the school to the post office.
