Which unit is used to express the speed of sound in seawater?

Explanation:
The speed of sound in seawater is a velocity, and the standard unit for velocity in scientific contexts is meters per second. In seawater, sound travels about 1500 m/s, though the exact value shifts with temperature, salinity, and depth. Using meters per second keeps the measurement consistent with the SI system and with other acoustic properties, making calculations and comparisons straightforward. Kilometers per hour or miles per hour are everyday-speed units not well-suited for the rapid propagation of sound, and miles per second would be far outside typical ranges. Therefore, the appropriate unit is meters per second.
