Both experianced interior painters can paint a 300-square-foot room in 250 minutes.

Explanation:

First interior painter can paint a 300-square-foot room in 200 minutes while the other interior painter can paint a 300-square-foot room in 300 minutes. If the work is evenly distributed, the first painter finish his work earlier that the second painter. The first painter can paint 150 square foot room in just 100 minutes while the second painter can paint 150 square foot room in 150 minutes so the work will be done in 250 minutes.
