Question

A color printer prints 32 pages in 11 minutes how many does it take per page

Answer 1

`\bf \begin{array}{ccll} pages&minutes\\ \cline{1-2} 32&11\\ 1&m \end{array}\implies \cfrac{32}{1}=\cfrac{11}{m}\implies m=\cfrac{1\cdot 11}{32}\implies m=\stackrel{\textit{about }20(1)/(2)\textit{ seconds}}{0.34375}`
