Give the distance and the speed you expect to hold, and this says how long the drive takes. Add a stretch for every change of road, add the time you will stop, and give a departure time to get the hour you arrive.

How it works

Each stretch takes its distance divided by its speed, and the drive is the sum of the stretches. That is why the average speed of a mixed journey is lower than a plain average of the speeds: the slow stretches take up more of the time.

The speed is the one you expect to average while moving, not the limit. Traffic, junctions and towns bring a real average below the signs, and nothing here guesses by how much — the figure you give is the figure used.

The comparison changes the speed of the first stretch only and keeps everything else, which answers the usual question: how much time does driving faster on the motorway actually save?

The table under the answer drives the first stretch ten faster, then ten more, up to forty above your speed. Each step saves less than the one before it, because the time is the distance divided by the speed. It goes on past any speed limit: it is arithmetic, not advice.

With a departure time, the comparison also gives the hour to leave at your own speed to arrive as early as the faster one would. With the consumption you measure at each speed and the price of fuel, it gives what the time saved costs, in litres per hundred kilometres, kilometres per litre, either kind of mile per gallon, or kilowatt-hours for an electric car. Nothing here estimates how much more a car burns when it goes faster: that depends on the car, and only its driver knows it.

Examples

Case Input Result
A single stretch 450 km at 110 km/h 4 h 5 min
Faster on the same road 450 km at 130 km/h instead of 110 38 min saved
Two kinds of road 300 km at 120 km/h, then 60 km at 70 km/h 3 h 21 min
Faster still 450 km at 150 km/h instead of 130 28 min saved

Frequently asked questions

Why is my average speed lower than the speeds I typed?

Because time, not distance, is what gets averaged. A stretch driven slowly lasts longer, so it weighs more in the average. 100 km at 50 km/h and 100 km at 100 km/h take three hours in all, an average of 66.7 km/h rather than 75.

Does it include traffic?

No. Nothing here knows the road you are taking or when. Use the speed you expect to average while moving, which on most journeys is below the limit, and add your stops as breaks.

How much time does driving faster save?

Less than it feels, and less the faster you already go: over 100 km, going from 110 to 130 km/h saves about 8 minutes, while going from 50 to 70 saves about 34. The comparison field works it out for your own journey.

Good to know

  • Rules on how long a driver may go without a rest differ by country and by vehicle, and none is applied here. Add the breaks you intend to take.
