In seismology, "slowness" is a term used to describe the inverse of seismic wave velocity. It is usually expressed in units of seconds per kilometer (s/km). While seismic wave velocity indicates how fast seismic waves travel through the Earth's materials, slowness provides a measure of how much time it takes for the wave to traverse a given distance.
