Speed Distance Time Calculator
Quickly find speed, distance, or time by providing the other two values with support for metric or imperial units.
speeddistancetime
Speed • Distance • Time
Solve one motion variable when you know the other two.
Speed
26.042 m/s · 93.75 km/h · 58.254 mph
Uniform motion
Speed = Distance ÷ Time
The calculator rearranges the fundamental distance = speed × time relationship depending on which variable you choose to solve for.
How to use
- Select which variable you want to solve for.
- Enter the known values and choose consistent units.
- Read the solved variable plus a reminder of the core equation.
Example
Input: Solve for time: Distance = 150 km, Speed = 90 km/h
Output: Time ≈ 1.67 hours (1 hour 40 minutes)
FAQ & notes
Can I convert the result to minutes or seconds?
Yes—toggle the display unit after solving to see the answer expressed in hours, minutes, or seconds.
Does it handle acceleration?
This panel assumes constant speed. Use the Force or Power calculators for scenarios that involve acceleration or energy.
