Multi-Leg Average Speed Calculator

Add journey legs and calculate total distance divided by total time, avoiding the common mistake of taking the simple arithmetic mean of leg speeds.

Distance unit

Time unit

—True average speed

—Total distance

—Total time

—mph

—m/s

Average speed = total distance ÷ total elapsed time

Do not average the individual leg speeds unless the time weights are equal.

Connected mechanics workflow

v10.88 connects translational motion, forces, momentum, energy, rotation, gravitation, waves and oscillation while preserving the established v2.3/v4.4/v10.38 physics engines.

State the model before trusting the number

Classical formulas are only as good as their assumptions and units. Air resistance, damping, deformation, non-constant forces and measurement uncertainty are not silently invented when the selected model does not include them.

How to use this Multi-Leg Average Speed Calculator

Add journey legs and calculate total distance divided by total time, avoiding the common mistake of taking the simple arithmetic mean of leg speeds.

What this tool calculates

Calculate true average speed across multiple distance and time legs.

Practical limits

These are constant-speed, straight-line planning calculations. Real movement can vary with acceleration, stops, route geometry, traffic, terrain, wind, and measurement error.
