we make a relation


\begin{gathered} (4)/(5)mi\longrightarrow(1)/(4)h \\ \\ 1mi\longrightarrow x \end{gathered}

where x is the number of hours that she takes to walk 1 mile

we solve using cross multiplication


\begin{gathered} x=(1mi*(1)/(4)h)/((4)/(5)mi) \\ \\ x=((1)/(4)h)/((4)/(5)) \\ \\ x=(5)/(16)h \end{gathered}

to walk 1 mile she takes 5/16 of an hour
