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?

3600 / [ 50 *20 ] =  3.6  sq ft / min  painted by one worker

 

So

 

4000 / [ 25 * 3.6 ]  ≈  44.44  min
