How do you find the average velocity over an interval?
Artist 52 [7]

If the moving object is undergoing constant acceleration, then

v_{\rm avg}=\dfrac{v_i+v_f}2

(take the average of the initial and final velocities, if they're given)

If you don't know the acceleration or initial/final velocities, then you have to resort to the usual definition,

v_{\rm avg}=\dfrac{\Delta x}{\Delta t}

where \Delta x is the change in position and \Delta t is the duration of the interval.
