Susan is installing junction boxes in a living room wall which is 12 feet long. she has to install two boxes evenly spaced on the wall with the center point of the wall centered between the boxes (as if all arrows are equal in the picture below). the junction boxes are 4 11/16 inches wide. how much wall space will be between the two boxes? (answer should be a mixed number, not a decimal.)

Wall space between two junction boxes is  

Step-by-step explanation:

Length of wall = 12 foot = 144 inches

Length of Junction box =

There are two junction boxes to be arranged.

Total length of junction boxes =

Space left:

Space =

Hence, wall space between two junction boxes is
