Auto, road trips and travel
This section links speed, time and distance so you can plan a departure, sanity-check a schedule or work out an average pace.
The calculations use a constant average speed and ignore traffic — compare with a navigation app for congested routes.
What you can calculate
- Average speed from distance and time.
- Travel time at a known speed.
- Distance covered in a given time.
Planning a long drive
Build stops into the plan: every two or three hours behind the wheel adds 15–20 minutes of rest, and fuel plus food adds roughly another half hour.
