A straight-line estimate — doesn't account for traffic, stops, or route.
How the Travel Time Calculator works
Choose what you want to find — time, speed, or distance — and enter the other two values. The calculator uses the simple relationship between distance, speed, and time to solve for the missing one.
Frequently asked questions
Does this account for traffic or stops?
No — this is a straight-line estimate based on distance and average speed. Real travel time can be longer with traffic, stops, or route detours.
Can I find the speed I need to arrive on time?
Yes — switch to "Find speed", enter your distance and available time, to see the average speed you'd need to maintain.
