The average speed of a moving object during a given interval of time is always:
Correct answer: A. the distance covered during the time interval divided by the time interval
- A. the distance covered during the time interval divided by the time interval
- B. the magnitude of its average velocity over the interval
- C. one-half its speed at the end of the interval
- D. its acceleration multiplied by the time interval
- E. one-half its acceleration multiplied by the time interval
Explanation
Average speed is defined as the total distance travelled divided by the total time taken. It is not always equal to the magnitude of average velocity because an object may change direction.
