Question

An object moves with speed $v_1, v_2$ and $v_3$ along a line segment $\mathrm{AB}, \mathrm{BC}$ and CD respectively as shown in figure. Where $A B=B C$ and $A D=3 A B$, then average speed of the object will be :

Select the correct option:

$\frac{\left(v_1+v_2+v_3\right)}{3}$

$\frac{v_1 v_2 v_3}{3\left(v_1 v_2+v_2 v_3+v_3 v_1\right)}$

$\frac{3 v_1 v_2 v_3}{v_1 v_2+v_2 v_3+v_3 v_1}$

$\frac{\left(v_1+v_2+v_3\right)}{3 v_1 v_2 v_3}$
