The meter per second (symbolized m/s or m/sec) is the Standard International ( SI ) unit of linear speed. This quantity can be defined in either of two senses: average or instantaneous.
Average linear speed is obtained by measuring the distance in meter s that an object travels in a certain number of second s, and then dividing the distance by the time. If s avgrepresents the average speed of an object (in meters per second) during a time interval t (in seconds), and the distance traveled in that time is equal to d (in meters), then:
