Travel Time Calculator
Time, distance and speed are locked together: knowing any two gives the third. Choose what you want to find, enter the other two, and get the answer — whether that is the length of a drive, how far you will get, or the average speed you need.

Frequently asked questions
Why will my real trip take longer?
The math assumes a constant average speed. If the speed you enter is your true door-to-door average (including slowdowns), the estimate is good; if it is your highway cruising speed, add time for stops and slower segments.
How do I estimate an average speed for a mixed trip?
A rough rule: use about 45–50 mph as the door-to-door average for mostly-highway US road trips, less with city driving. Or solve backwards from a past trip with this calculator.
Can I use this for running or cycling pace?
Yes — enter distance and time in the speed mode to get average speed, or distance and speed for your finishing time. Minutes-per-mile pace is speed turned upside down: 60 ÷ mph.
