m/sec is the unit of velocity.
Step-by-step explanation:
The displacement is a vector quantity. It is a measure difference between the end and start point of a moving object.
The displacement of an object is measured in metres, kilometers, centimeter or inches. But the SI unit of displacement is always converted to metres.
The time may be in minutes, hours or second, but the SI unit of time is sec
velocity with respect to displacement is defined as rate at which displacement changes with time.
from the formula :
velocity=diplscement/time
= m/sec
So the SI unit of velocity is m sec
