Explanation

 "Meter per second" (m/s) is the standard unit of speed and velocity,

Indicating the distance traveled in meters throughout one second.

It measures how fast something moves (speed) and in what direction (velocity). 

Speed:

Speed is a scalar quantity, meaning it only describes the magnitude (how fast) of an object's movement, measured in meters per second. 

Velocity:

Velocity is a vector quantity, meaning it describes both the magnitude (how fast) and direction of an object's movement, also measured in meters per second.
