Explanation:

30.

Step1: Divide total area by number of ads

We divide the total available area by the number of ads to find the area per ad. The total area is 63 square - inches and the number of ads is 4.
$63\div4=\frac{63}{4}= 15.75$ square - inches

Step1: Divide total money raised by price per sub

We know the total money raised is $117 and the price per sub is $3.25. We divide the total money by the price per sub to find the number of subs sold.
$117\div3.25=\frac{117}{3.25}=36$

Step1: Recall the velocity formula

Velocity $v=\frac{d}{t}$, where $d$ is the distance and $t$ is the time. Here, $d = 882\frac{1}{2}=\frac{882\times2 + 1}{2}=\frac{1764 + 1}{2}=\frac{1765}{2}$ feet and $t = 5$ seconds.
$v=\frac{\frac{1765}{2}}{5}=\frac{1765}{2}\times\frac{1}{5}=\frac{1765}{10}=176.5$ feet per second

Answer:

15.75 square inches
