The answer is 3520 per minute.. because there is 5280 feet in a mile, then you x that by 40 since there's 40 miles. Then you divide by 60 cause there's 60 minutes in an hour.
calculista

we know that

[tex]1\ mile=5,280\ feet\\ 1\ hour=60\ min[/tex]

we have

[tex]40\frac{miles}{hour}[/tex]

Step [tex]1[/tex]

Convert  [tex]\frac{miles}{hour}[/tex] to [tex]\frac{feet}{hour}[/tex]

[tex]40\frac{miles}{hour}=40*5,280=211,200\frac{feet}{hour}[/tex]

Step [tex]2[/tex]

Convert  [tex]\frac{feet}{hour}[/tex] to [tex]\frac{feet}{min}[/tex]

[tex]211,200\frac{feet}{hour}=211,200/60=3,520\frac{feet}{min}[/tex]

therefore

the answer is

[tex]3,520\frac{feet}{min}[/tex]
