What is the relationship between speed, distance and time?

The basic formula is Speed = Distance ÷ Time. You can rearrange it to Distance = Speed × Time or Time = Distance ÷ Speed.

Can I convert units within the calculator?

Yes, the calculator typically supports unit conversions such as km/h, m/s, miles/h, and will convert inputs as needed.

Average speed = Total Distance ÷ Total Time. Do not average the separate speeds directly unless time is equal for each leg.

Select what to calculate:

Distance (km)

Time (hours)

What is the basic relationship between speed, distance and time?

The basic formula is: Speed = Distance ÷ Time. Rearranged: Distance = Speed × Time, Time = Distance ÷ Speed.

Can this calculator convert units?

Yes — it commonly supports unit conversions like km/h, m/s, miles/h and will convert inputs as required.

How do I calculate average speed for multiple legs?

Average speed = Total Distance ÷ Total Time. Do not simply average leg speeds unless each leg has equal time duration.

Does the calculator handle acceleration or variable speed?

Basic SDT calculators assume constant speed. For acceleration or variable speed, you need a more advanced physics-based approach.
