Estimate travel time from an average speed rather than a speed limit.
Use the Travel Time Calculator alongside this illustrative example.
A practical example
A 120 km journey averaging 60 km/h takes two hours of movement. Add a planned 20-minute stop and the total becomes two hours twenty minutes. Entering a motorway speed of 100 km/h for the entire journey would hide slower access roads and time spent stopped.
Check the result
Use the distance for the intended route, then compare a normal and a slower average-speed assumption. The gap between those estimates is more useful for planning than a single optimistic arrival time.
Try a comparison
Reduce the hypothetical average from 60 km/h to 40 km/h for the same 120 km route. Movement time rises from two to three hours. Keep stops separate so the comparison changes one assumption instead of concealing extra delays inside the speed.
What this does not establish
This calculator does not route around traffic, closures or weather. Consult a current navigation service for the route and leave an appropriate margin.
