Final answer:
The formula for average speed is total distance divided by total time. It can be calculated by dividing the distance traveled by the time it took for the object to change its position.
Step-by-step explanation:
The formula for average speed is:
average speed = total distance / total time
where total distance is the distance traveled by the object and total time is the time it took for the object to change its position.
For example, if an object travels a total distance of 100 meters in a total time of 20 seconds, the average speed would be:
average speed = 100 meters / 20 seconds = 5 meters per second.
