A point traversed half of the distance with a velocity $v_0$. The remaining part of the distance was covered with velocity $v_1$ for half the time and with velocity $v_2$ for the other half of the time. The mean velocity of the point averaged over the whole time of motion is

  • A

    $\frac{v_0+v_1+v_2}{3}$

  • B

    $\frac{2 v_0+v_1+v_2}{3}$

  • C

    $\frac{v_0+2 v_1+2 v_2}{3}$

  • D

    $\frac{2 v_0\left(v_1+v_2\right)}{\left(2 v_0+v_1+v_2\right)}$
