How this calculator works
Distance divided by average speed gives travel time. This assumes a constant trip average and excludes separate rest stops. Average speed must be positive; a zero-length trip takes zero time.
The formula
Hours = distance (km) / speed (km/h)A quick example
350 km at 90 km/h takes about 3 hours 53 minutes (3 hours 53 minutes 20 seconds).
