how many minutes does it take 4 people to paint 6 walls?

27 minutes

Step-by-step explanation:

Given that:

It takes 16 minutes for 9 people to paint 8 walls.

i.e

16 minutes ------------ 9 people ---------- 8 walls

How many minutes does it take 4 people to paint 6 walls?

let the number of minutes be (m). NOW;

(m) minutes ------------ 4 people ------------ 6 walls

If it takes 16 minutes for 9 people to paint 8 walls.

∴ For 1 person to paint 8 walls; it will take 16 minutes × 9 = 144 minutes

So, to determine the number  of minutes it will take 1 person to paint 6 walls; we have;

6 walls =

6 walls × 144 minutes = 8 walls ×  (m)

(m) =

m = 108 minutes

So, it will take 108 minutes for one person to paint 6 walls.

For 4 people now; we have

m =

m= 27 minutes

∴ it will take 27 minutes for  4 people to paint 6 walls
