<span>Randall’s family drove to the beach for vacation. Assume they drove the same speed throughout the trip. The first day, they drove 130miles in 22 hours. The second day, they drove 325 miles in 55 hours. The third day, they arrived at the beach by driving 390 miles in 66 hours.</span>
The average change per hour is B 40.7

Explanation
![9-\sqrt[]{-64}](https://tex.z-dn.net/?f=9-%5Csqrt%5B%5D%7B-64%7D)
Step 1
Let's remember that
A complex number is an object of the form

where a and b are real numbers and
![\begin{gathered} i^2=-1 \\ i=\sqrt[]{-1} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20i%5E2%3D-1%20%5C%5C%20i%3D%5Csqrt%5B%5D%7B-1%7D%20%5Cend%7Bgathered%7D)
so
![\begin{gathered} 9-\sqrt[]{-64} \\ 9-\sqrt[]{-1\cdot64} \\ 9-\sqrt[]{-1}\sqrt[]{64} \\ 9-8\sqrt[]{-1} \\ 9-8i \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%209-%5Csqrt%5B%5D%7B-64%7D%20%5C%5C%209-%5Csqrt%5B%5D%7B-1%5Ccdot64%7D%20%5C%5C%209-%5Csqrt%5B%5D%7B-1%7D%5Csqrt%5B%5D%7B64%7D%20%5C%5C%209-8%5Csqrt%5B%5D%7B-1%7D%20%5C%5C%209-8i%20%5Cend%7Bgathered%7D)
therefore, the answer is

I hope this helps you
The solution lies in quadrant I
