Just solving the problem as directly as you can may be best.

Painter___________rate__________time___________Amount of jobs
Me________________1/4___________4______________1
Apprentice________1/6___________6______________1
Both of us_______1/4+1/6_______(?)_____________1

Our rate, both of us together, is jobs per hour. That rate is 5/12 jobs per hour. Since we really want how many hours per 1 job, we want the reciprocal of 5/12, which is hours. This is definitely a few minutes LESS THAN two and a half hours.
