He receives an average of one computer every 55 minutes to repair. It takes him an average of 45 minutes to repair any of these computers.

He estimates that adding an assistant, but still keeping the department running as a single-server system, would allow computer2 to be repaired in half the time, an average of 22.5 minutes to repair these computers.
