All members of our painting team paint at the same rate. If $50$ members can paint a $3600$ square foot wall in $20$ minutes, then how long would it take for $25$ members to paint a $4000$ square foot wall, in minutes?

Number of  square ft painted in one  minute =  3600 / 20  =  180

Number of square ft  painted in one minute by one  person =  180 / 50  = 3.6 sq ft

 

Then 25 people can paint   25 * 3.6  = 90sq ft  in one minute

 

So....the number of  minutes to paint a 4000 sq ft wall =  4000  / 90   ≈  44.4  min
