Walking
1.389 m/s - Speed; example.
Walking is a form of human locomotion where one foot is always in contact with the ground.
A constant 5 km/h walking model, excluding stops.

Measurements, assumptions & sources
Light in vacuum
100% of c (1c) - Speed; exact.
Light in vacuum is electromagnetic radiation that travels through empty space without any material medium.
Exactly 299,792,458 metres per second in vacuum. Light travels more slowly through materials.
