Explanation:

Step1: Identify coordinates

The coordinate of point G is $\frac{1}{2}$, and the coordinate of point V is $2\frac{1}{2}=\frac{5}{2}$.

Step2: Calculate distance

The distance $d$ between two points on a number - line is $d=\vert x_2 - x_1\vert$. Here, $x_2=\frac{5}{2}$ and $x_1 = \frac{1}{2}$, so $d=\vert\frac{5}{2}-\frac{1}{2}\vert$.
$d=\vert\frac{5 - 1}{2}\vert=\vert\frac{4}{2}\vert = 2$.
