You know this, I know you know it, because. You know that speed is distance traveled over time taken: 100 meters * 1mi / 1609 meters / 5 seconds. Where I converted to miles from meters using our old trick.

If you need to convert to miles per hour, then multiply your result time 1 hour / 3600 seconds, same trick as before.
