Question

Which of the following relation represents the relationship between the average speed, time, and distance correctly?

• A. Average speed = distance × time
• B. Average speed = $\frac{\mathrm{Total}\mathrm{distance}}{\mathrm{Total}\mathrm{time}}$
• C. Time = average speed + distance
• D. Distance = average speed × (time)²

Answer 1

The correct option is B

Average speed = $\frac{\mathrm{Total}\mathrm{distance}}{\mathrm{Total}\mathrm{time}}$

1. Distance is the actual path length taken by a body.
2. Its SI unit is meter (m).
3. Average speed is equal to the total distance covered by the body divided by the total time taken by the body to cover that distance.
4. $\mathrm{Average}\mathrm{speed}=\frac{\mathrm{Total}\mathrm{distance}\mathrm{covered}}{\mathrm{Total}\mathrm{time}\mathrm{taken}}$

Thus, option B is correct.
