Which statement is <strong>always</strong> true for any straight-line trip?
Average speed ≥ average velocity magnitude.
Average speed = average velocity magnitude.
Average speed is unrelated to displacement.
Average speed ≤ average velocity magnitude.
Explanation
Total distance |displacement|, so average speed |average velocity|. They are equal only if motion is one-directional.
