When to use this calculator
Estimate moving time from distance and average speed. Add breaks, traffic delays and stops separately.

PUTTING IT INTO PRACTICE
Journey Time: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Distance (km) | 180 |
| Average speed (km/h) | 60 |
| Result | 3 hours |
- Check the input labels and enter the example values above.
- Apply the relationship: Time = distance ÷ average speed.
- The result is 3 hours, rounded for display.
How to interpret your result
Add breaks, traffic delays and stops separately.
Average speeds should include the delays relevant to your question. Equal-distance and equal-time speed averages use different methods. Compare trip budgets with consistent expense categories and journey boundaries.
Frequently asked questions
Why is average speed for equal-distance legs not a simple average?
More time is spent on the slower leg. Divide total distance by total travel time, which produces the harmonic mean for two equal-distance legs.
How do I use the journey time calculator?
Enter distance (km), average speed (km/h). The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
Time = distance ÷ average speed.
What should I check before using the result?
Add breaks, traffic delays and stops separately.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
