Step 1
Coordinates of A are (0, 0) and R be (23, 0)
Step 2
Using mid-point formula,
Coordinate of mid point be $\left(\frac{{x}_{1}+{x}_{2}}{2},\frac{{y}_{1}+{y}_{2}}{2}\right)$
Thus, coordinates of mid-point:
$AR=\left(\frac{0+23}{2},\frac{0+0}{2}\right)$
$=\left(11.5,0\right)$
Answer: $\left(11.5,0\right).$
