Speed from Time and Distance
Calculate average speed and total time for a drive.
About Speed from Time and Distance
Converting the elapsed time to total minutes and dividing the miles by it produces the average speed, scaled to miles per hour. Planners use average speed to set realistic ETAs, accounting for stops that a pure cruise speed estimate would ignore.
Formula
Speed from Time and Distance
Speed = distance x 60 / total minutes
- total minutes
- Hours and minutes expressed as one minute count
Worked example
With the default values below, Speed from Time and Distance returns Average Speed of 66.7. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is Speed from Time and Distance calculated?
Speed = distance x 60 / total minutes Converting the elapsed time to total minutes and dividing the miles by it produces the average speed, scaled to miles per hour.
Why does Speed from Time and Distance matter?
Planners use average speed to set realistic ETAs, accounting for stops that a pure cruise speed estimate would ignore.
