Speed, Distance & Time Calculator
Solve for velocity, travel time, or distance with instant multi-unit conversion between miles, kilometers, hours, and minutes.
60.00 km/h
What is the Speed, Distance, and Time Relationship?
The relationship between speed, distance, and time is fundamental to classical mechanics. Speed ($v$) is defined as the scalar rate of change of position, calculated as total distance divided by time elapsed ($v = d / t$). Using simple algebraic rearrangement, Distance ($d = v imes t$) and Time ($t = d / v$) can be directly determined from any two known quantities.

Frequently Asked Questions
What is the difference between speed and velocity?
Speed is a scalar quantity representing how fast an object moves regardless of direction. Velocity is a vector quantity that specifies both speed and directional orientation (e.g. 60 mph North).
What is the SI unit for speed?
The International System of Units (SI) standard for speed is meters per second (m/s). 1 m/s = 3.6 km/h ≈ 2.237 mph.
