Input & settings
Ready. Enter your input to begin.
How to use this tool
Choose the unknown and fill the other two fields. The field for the chosen unknown is ignored. Speed = distance ÷ time.
Limits and behavior
Results use floating-point arithmetic, rounded to 12 significant digits. Inputs are limited to an absolute value of 10^12 and results to 10^15. Constant or average speed is assumed. A divisor must be positive. Input is limited to 1 MB and output to 3 MB. No input content is saved by CraftAI.
Solve common speed, distance and time equations
Enter two supported quantities to calculate the remaining quantity under constant average speed assumptions.
Does constant speed account for traffic or acceleration?
No. It is a mathematical model rather than a full travel or vehicle simulation.
