All of the members of our spray-painting team paint at the same speed. If 5 team members can paint a certain wall in 27 minutes, then how many minutes would it take 15 of our team members to paint the same wall?

 

Thanks and if possible please explain why?

Note that 15  members will paint 3 times as fast as 5  members

 

So....15 members will paint the wall in 1/3  of the time as 5 members  =  (1/3)* 27  = 9 minutes
