<br>
average speed = total distance / total time
Calculate the average speed of the person during the 2000 seconds. Use your answer to Question 05.2.
<br>
Use the equation:
<br>
average speed = total distance / total time
How to approach this question
1. Use the total distance you found in Q05.2 (3250 m).
2. The total time is given as 2000 s.
3. Substitute these values into the equation for average speed.
4. Calculate the result and give the correct units.
Full Answer
average speed = 3250 m / 2000 s
average speed = 1.625 m/s
The equation is: average speed = total distance / total time.
From Q05.2, the total distance is 3250 m.
The total time is 2000 s.
Substitute the values:
Average speed = 3250 / 2000
Average speed = 1.625 m/s
Common mistakes
✗ Using an incorrect distance from the previous question (error carried forward is usually allowed).\n✗ Dividing time by distance.\n✗ Forgetting the units (m/s).
