30/4=7.5. 7.5 minutes every mile... That means that she ran 75 minutes

$\bf \begin{array}{ccllll} miles&minutes\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ 4&30\\ 10&x \end{array}\implies \cfrac{4}{10}=\cfrac{30}{x}$

solve for "x"
