MCQ
Which of the following statement is correct?
- AAverage speed > Instantaneous speed.
- BAverage speed >= Instantaneous speed.
- CAverage speed <= Instantaneous speed.
- DAverage speed < Instantaneous speed.
✓
Answer
- Average speed <= Instantaneous speed.
Explanation:
Average speed is the ratio of total distance to total time. Instantaneous speed is the ratio of instantaneous change in distance to instantaneous change in time. Average speed can be equal to instantaneous speed but is usually less than that.
