Answer 1

-- 5 people paint 5 walls in 52 minutes.

-- 5 people paint 1 wall in (52/5) minutes

-- 1 person could paint 1 wall in (5)x(52/5) = 52 minutes

-- 1 person could paint 20 walls in (52 x 20) = 1,040 minutes

-- 20 people could paint 20 walls in (1,040/20) = 52 minutes

===============================================

An easier way:

-- 5 people paint 5 walls in 52 minutes

-- If there are 20 walls, that's 4 times as much work.  If you put 4 times as many people on the job, they can get it done in the same amount of time . . . . . 52 minutes.
