Answer :

We have,
1 mile = 5280 feet
32 miles = 5280 * 32
              = 168960 feet

1 hour = (60 * 60) = 3600 seconds

Now,
Converting 32 miles per hour to feet per second.

[tex] \frac{32~miles}{1~hour} [/tex]

[tex]= \frac{168960 ~feet}{3600~ seconds} [/tex]    because 32 miles is 168960                                                                                         feet and 1 hour is 3600                                                                                                 seconds
[tex]= \frac{46.93~feet}{1~second} [/tex]

So, the answer is 46.93 feet per second
