48 feet per second

#### Explanation:

Write as $\frac{144}{3}$ but for unit rate we need ?/1

So we need to change the 3 into 1. We can do this by dividing it by 3. Using the rule: "what you do to the bottom you also do to the top" (this does not work for add or divide).

Divide the top and bottom by 3

$\frac{144}{3} \text{ "->" "(144-:3)/(3-:3) " "->" } \frac{48}{1}$

So feet per second

$\text{ "->" "("feet")/("seconds")" "->" "48" feet per second}$
