Question

Rob travels 132 miles per hour. How long does it take him to travel 11 miles? Your answer should be in hours, accurate to at least the nearest tenth ​

Answer 1

keeping in mind that 1 hour has 60 minutes, then

`\begin{array}{ccll} miles&minutes\\ \cline{1-2} 132 & 60\\ 11& x \end{array} \implies \cfrac{132}{11}=\cfrac{60}{x}\implies 12=\cfrac{60}{x} \\\\\\ 12x=60\implies x=\cfrac{60}{12}\implies x=5`
