Plug (Posted on 2024-03-19)

A room has a 20-foot ceiling. From the ceiling hang two electrical cords 16 feet and 18 feet long.

At the end of one is a plug, and at the end of the other is a receptacle. The electrician is tall, and can reach up to 8 feet from the floor.

How far apart can the two cords be, yet still be possible for the electrician to connect them?
