Answer:
The answer is 60 minutes.
Step-by-step explanation:
If the experienced painter can paint a wall in 20 minutes, and the inexperienced painter can do one in 60 minutes, then the inexperienced painter can paint one wall, and the experienced painter can paint three walls. They will both take 60 minutes and finish at the same time. Therefore, it will take them sixty minutes.
