Answer:
Speed tells us how fast something or someone is traveling. You can find the average speed of an object if you know the distance travelled and the time it took. The formula for speed is speed = distance ÷ time.
Explanation:
Doubling one's speed would mean doubling one's distance traveled in a given amount of time. ... In order to calculate the speed of an object we must know how far it's gone and ... The slowest speeds are measured over the longest time periods.
I hope this helps :)
