The Question is not difficult i want  try to give you simple explanation on it :

If 20 members can paint a 2000 square foot wall in 40 minutes, we can calculate the rate of painting per minute for the team.

The rate of painting for the team is:
2000 square feet / 40 minutes = 50 square feet per minute

Now, let's determine how long it would take the 20 members to paint a 6000 square foot wall.

Time = Area / Rate
Time = 6000 square feet / 50 square feet per minute
Time = 120 minutes

Therefore, it would take the 20 members 120 minutes to paint a 6000 square foot wall.
