Instantaneous speed

Summary: The speed that the runner is travelling at any time during the race is the instantaneous speed. This is the speed that you see on the speedometer in a car. You can work out the average speed by dividing the total distance by the total time that it took to run the race. This average speed makes it easier to compare how fast different people, boats, or cars travel. Tags: science student-book-7 physics Created: 2026-05-21 Last Updated: 2026-05-21
