Question

Monica can walk 4/5 of a mile in 1/4 of an hour. b. How long does it take her to walk 1 mil?

Answer 1

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
