## Problem

Could someone help me with this problem? I'm totally lost.

An experienced typist can type a brief in 6 hours. Her assistant can type the same brief in 9 hours. If they both work together for 3 hours and then the experienced typist work alone, how many hours will it take her to finish the job?

Thanks,
