How this tool handles your input
Choose the missing quantity and enter the other two. Speed = distance ÷ time; distance = speed × time; time = distance ÷ speed.
Inputs are non-negative; divisors must be positive. This assumes constant or average speed and does not model stops or acceleration.
Example: 120 km over 2 h → 60 km/h
