Answer:
Wall space between two junction boxes is [tex]44\displaystyle\frac{7}{8}\text{ inches}[/tex]
Step-by-step explanation:
We are given the following information:
Length of wall = 12 foot = 144 inches
Length of Junction box = [tex]4\displaystyle\frac{11}{16}\text{ inches}[/tex]
There are two junction boxes to be arranged.
Total length of junction boxes = [tex]8\displaystyle\frac{11}{16}\text{ inches}[/tex]
Space left:
[tex]\text{Length of wall} - \text{Length of junction boxes}\\= 144 -8\displaystyle\frac{11}{16}\\= \displaystyle\frac{2154}{16} [/tex]
Now, this left space have to be distributed in three equal part so that the arrangement could be of the form: space, junction box, space, junction box, space.
Space = [tex]\displaystyle\frac{2154}{16} \div 3=\displaystyle\frac{2154}{48} = 44\displaystyle\frac{7}{8}[/tex]
Hence, wall space between two junction boxes is [tex]44\displaystyle\frac{7}{8}\text{ inches}[/tex]
