If 50 outlets are installed and 1,020 feet of cable are used, what is the average feet of cable per outlet?

• A. 19 feet
• B. 20.4 feet
• C. 21 feet
• D. 22 feet

Answer: (B)

The average per outlet is found by dividing the total cable length by the number of outlets. So, 1,020 feet ÷ 50 outlets = 20.4 feet per outlet. This means if you spread the cable evenly, each outlet would use 20.4 feet. The other options would imply different total lengths (for example, 19 feet per outlet would require 950 feet, 21 feet would require 1,050 feet, etc.), which doesn’t match the given total.
