Here is the solution...
![6i\sqrt{-44}](https://tex.z-dn.net/?f=6i%5Csqrt%7B-44%7D)
<u>Step 1:</u>
We need rewrite the square root -44 as
.
The reason is ![\sqrt{-1} = i](https://tex.z-dn.net/?f=%5Csqrt%7B-1%7D%20%3D%20i)
<u>Step 2:</u>
Now the expression became ![-6i.i\sqrt{44}](https://tex.z-dn.net/?f=-6i.i%5Csqrt%7B44%7D)
![-6i^{2}\sqrt{4*11}](https://tex.z-dn.net/?f=-6i%5E%7B2%7D%5Csqrt%7B4%2A11%7D)
<u>Step 3:</u>
![i^{2} = -1 and\sqrt{4*11} = 2\sqrt{11} \\](https://tex.z-dn.net/?f=i%5E%7B2%7D%20%3D%20-1%20and%5Csqrt%7B4%2A11%7D%20%3D%202%5Csqrt%7B11%7D%20%5C%5C)
Now substitute the above values in the step 2, we get
![-6(-1)2\sqrt{11}](https://tex.z-dn.net/?f=-6%28-1%292%5Csqrt%7B11%7D)
<u>Step 4:</u>
We have to simplify it.
12![\sqrt{11}](https://tex.z-dn.net/?f=%5Csqrt%7B11%7D)
<u>Therefore, the answer is 1
</u>

To find the rate in miles per hour, divide the miles by the hours.
(1 1/2 miles)/(3/5 hour) =
= 3/2 miles * (5/3 hour)
= 5/2 mph
= 2 1/2 mph
Her walking rate is 2 1/2 mph.
(4 1/2 miles) / ( 2 1/2 mph) =
= 9/2 miles / (5/2 mph)
= 9/2 * 2/5 hours
= 9/5 hours
= 1 4/5 hours
From 9:00 a.m. to 11 a.m., she has 2 hours, but she only needs 1 4/5 hours to walk, so she will make it to work on time.
Initial volume = 2 1/6
1/8 of that volume
1/8 of 2 1/6
1/8 * 13/6
13 / 48
