Is this formula is true according to Heisenberg uncertainty principle?

the formula that describes the velocity is equal to the change of the displacement over the change of time,,,,, is this formula true according to heisenberg uncertainty principle? specially it is impossible measuring the displacement and momentum at the time.

HUP does not limit the accuracy of velocity measurement.
HUP refers to "conjugate variables" like p and x.
x and t are not conjugate variables.
