Convert miles per hour to miles per minutes, we can note that:
[tex]1hour=60\text{minutes}[/tex]Then:
[tex]\frac{mi}{h}=\frac{mi}{60\min }[/tex]Thus, to find the rate of miles per minutes, we divide the velocity by 60:
[tex]57\frac{mi}{h}=\frac{57}{60}\frac{mi}{\min }=0.95\frac{mi}{\min}[/tex]That's the answer to the first question. To find the miles traveled in 5 minutes, since we have the ratio in minutes we need to multiply the ratio by the time:
[tex]0.95\frac{mi}{\min}\cdot5\min =4.75mi[/tex]That's the answer to the second question.
