Answer:

<h2>The construction crew has a speed of 2.75 feet per hour.</h2>

Step-by-step explanation:

In this problem, we have to find the unit rate, that is, the distance deep per hour, which can be also determined as the speed of the crew.

We know that after 3 hours, the hole is 8.25 feet deep. To find the unit rate we need to divide

$s=\frac{8.25ft}{3hr}=2.75 \ ft/hr$

Therefore, the construction crew has a speed of 2.75 feet per hour, that's the unit rate.
