\textbf{Given:}

\textsf{Parallel lines are}

\mathsf{3x+4y=5}

\mathsf{6x+8y=45}

\textbf{To find:}

\textsf{The distance between the given parallel lines}

\textbf{Solution:}

\underline{\textsf{Formula used:}}

\mathsf{The\;distance\;between\;the\;parallel\;lines\;ax+by+c_1=0\;and\;ax+by+c_2=0\;is}

\boxed{\mathsf{\left|\dfrac{c_1-c_2}{\sqrt{a^2+b^2}}\right|}}

\textsf{The given parallel lines can be written as}

\mathsf{3x+4y-5=0}

\mathsf{3x+4y-\dfrac{45}{2}=0}

\underline{\textsf{The distance between the given parallel lines}}

\mathsf{=\left|\dfrac{c_1-c_2}{\sqrt{a^2+b^2}}\right|}}

\mathsf{=\left|\dfrac{-5+\dfrac{45}{2}}{\sqrt{3^2+4^2}}\right|}}

\mathsf{=\left|\dfrac{\dfrac{-10+45}{2}}{\sqrt{9+16}}\right|}}

\mathsf{=\left|\dfrac{\dfrac{35}{2}}{\sqrt{25}}\right|}}

\mathsf{=\left|\dfrac{\dfrac{35}{2}}{5}\right|}}

\mathsf{=\left|\dfrac{35}{2{\times}5}\right|}}

\mathsf{=\left|\dfrac{35}{10}\right|}}

\mathsf{=\left|\dfrac{5}{2}\right|}}

\mathsf{=\dfrac{5}{2}\;units}}

\mathsf{=2.5\;units}}

\textbf{Answer:}

\textsf{The distance between the given parallel lines is 2.5 units }
