All of the members of our spray-painting team paint at the same speed. if 8 team members can paint a certain wall in 36 minutes, then how many minutes would it take 18 of our team members to paint the same wall?
If it took 8 persons, each working 36 minutes, to paint a wall,
then it took a grand total of 8 x 36 = 288 minutes.
If it takes a total of 288 minutes, and you have 18 persons,
divided equally, each person would work 288 / 18 = 16 minutes.
