5 metres per second
Speed: 5 m/s; definition.
The quantity is exact as entered. Comparisons use the clearly stated specimen, model or nominal measurement.
Pedal-powered rail trolley
Defined operating speed: 5 m/s; defined specimen; range 3 m/s–7 m/s.
A defined four-seat pedal rail trolley 2.4 m long, 250 kg ready to ride and travelling at 5 m/s. Commercial rail bikes differ; length excludes couplers and the mass excludes riders.
The marked defined operating speed is calibrated. Unmeasured illustration details are representative.

How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- We use 5 m/s for the operating speed of a pedal-powered rail trolley; the recorded range is 3 m/s–7 m/s.
- The operating speed of a pedal-powered rail trolley: This is an illustrative comparison value, not a claim that every example is the same.
- The recorded ranges overlap, so the ordering can vary even though the central values differ.
Speed is distance per unit time; it does not specify the total distance travelled.
