Time Calculator
Calculate how long a journey takes given a distance and a constant speed.
How it works
- 1Enter the distance travelled and the constant speed of the object.
- 2Choose metric (m, m/s) or imperial (ft, ft/s) units using the toggle at the top.
- 3The calculator applies t = d ÷ v and displays the result in seconds, minutes, and hours.
Use cases
- Estimating journey duration when driving at a known average speed.
- Physics and engineering problems involving uniform linear motion.
- Comparing travel times across different speeds for the same route.
Frequently asked questions
What formula does this calculator use?
It uses t = d ÷ v, where t is time in seconds, d is distance in metres, and v is speed in metres per second. For example, travelling 100 m at 25 m/s gives t = 100 ÷ 25 = 4 s.
Why does the result show “—” when I enter a speed of 0?
Division by zero is undefined — an object moving at zero speed never covers any distance, so time is meaningless in that context. Enter any positive speed to get a result.
Can I use imperial units?
Yes. Switch to imperial with the toggle at the top and enter distance in feet (ft) and speed in feet per second (ft/s). The calculator converts both values to SI internally before computing, so the physics is always accurate.
