distance between two points can be calculates using :
${P}_{1}=\left({x}_{1},{y}_{1},{z}_{1}\right)\phantom{\rule{1ex}{0ex}}\text{}\phantom{\rule{1ex}{0ex}}{P}_{2}=\left({x}_{2},{y}_{2},{z}_{2}\right)$
$\Delta s=\sqrt{{\left({x}_{2}-{x}_{1}\right)}^{2}+{\left({y}_{2}-{y}_{1}\right)}^{2}+{\left({z}_{2}-{z}_{1}\right)}^{2}}$
$\Delta s=\sqrt{{\left(7-7\right)}^{2}+{\left(-24+46\right)}^{2}+{\left(7-1\right)}^{2}}$
$\Delta s=\sqrt{484+36}$
$\Delta s=\sqrt{520}$
$\Delta s=22.8\phantom{\rule{1ex}{0ex}}\text{}\phantom{\rule{1ex}{0ex}}unit$
