Frequently Asked Questions
What is the core formula?
Distance = Speed × Time. Rearranged: Speed = Distance ÷ Time, and Time = Distance ÷ Speed.
Do the units need to match?
Yes — make sure distance, speed and time use consistent units (e.g. kilometers, kilometers per hour, and hours) or the result won't be meaningful.
