William can do 1/4 of the job every hour by himself.

Stephanie can do 1/6 of the job every hour by herself.

If they don't distract each other while working together, they can do (1/4 + 1/6) of the job every hour.

That's (3/12 + 2/12) = 5/12 job per hour working together.

The complete job will take them (12/5) hour .

That's 2-2/5 hours, or 2 hours 24 minutes.

They both can do the painting in 2hours 24 minutes by solving the fraction.
