Answer:

[tex]22.62\frac{ft}{sec}[/tex]

Step-by-step explanation:

we know that

[tex]1\ mi=5,280\ ft[/tex]

To convert miles to feet multiply by 5,280

[tex]1\ min=60\ sec[/tex]

To convert minutes to seconds multiply by 60

we have

[tex]3\ min\ 53.43\ sec=3(60)+53.43=233.43\ sec[/tex]

To find out the speed in feet per second, divide the distance in feet by the time in seconds

so

[tex]\frac{5,280}{233.43}=22.62\frac{ft}{sec}[/tex]
