notice the proportions below. Keep in mind that 1 hour is 60 minutes.

[tex]\bf \begin{array}{ccll} miles&minutes\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 0.75&1\\ x&60 \end{array}\implies \cfrac{0.75}{x}=\cfrac{1}{60}\implies \cfrac{0.75\cdot 60}{1}=x\implies 45=x[/tex]
