Answer : She will hike about 18 kilometers in 6 hours .
Explanation :
Since we have given that
on every 4 hours , she hikes about 12 kilometers
![\text{on every 1 hour, she hikes about }\frac{12}{4}\text{ kilometers}](https://tex.z-dn.net/?f=%5Ctext%7Bon%20every%201%20hour%2C%20she%20hikes%20about%20%7D%5Cfrac%7B12%7D%7B4%7D%5Ctext%7B%20kilometers%7D)
![i.e. 3\text{ kilometers}](https://tex.z-dn.net/?f=i.e.%203%5Ctext%7B%20kilometers%7D)
![\text{So , every 6 hours, she hikes about =}6\times 3\text{kilometers}=18\texr{ kilometers](https://tex.z-dn.net/?f=%5Ctext%7BSo%20%2C%20every%206%20hours%2C%20she%20hikes%20about%20%3D%7D6%5Ctimes%203%5Ctext%7Bkilometers%7D%3D18%5Ctexr%7B%20kilometers)
Hence, she will hike about 18 kilometers in 6 hours .

Answer:
<em>The unit rate for the price to the length of the fabric will be $8 per meter.</em>
Step-by-step explanation:
The two points on the graph of the line are: (1, 8) and (3, 24)
For finding the unit rate for the price to the length of the fabric, we just need to find the slope of that line.
Formula for finding the slope is:
, where
and
are two given points.
Here,
and ![(x_{2}, y_{2})=(3, 24)](https://tex.z-dn.net/?f=%28x_%7B2%7D%2C%20y_%7B2%7D%29%3D%283%2C%2024%29)
So, the slope of the line will be: ![m= \frac{24-8}{3-1}= \frac{16}{2}= 8](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B24-8%7D%7B3-1%7D%3D%20%5Cfrac%7B16%7D%7B2%7D%3D%208)
Thus, the unit rate for the price to the length of the fabric will be $8 per meter.
