How to deduce the formula of velocity in the middle position of uniform acceleration motion

The initial velocity is V0, the final velocity is V, the final velocity is V, and the velocity in the middle is V (1 / 2), the velocity in the middle is V (1 / 2), and the velocity in the middle is V (1 / 2) and the velocity in the middle is V (1 / 2) and the velocity in the middle is V (1 / 2) by x = v0t + 1 / 2at and V = V0 + 1 / 2at \35\\35\\\\\\\\\\\\\\\\\\\\\\\\\\\\\it's not easy
