7 PEOPLE PAINT 8 WALLS IN 24 MINUTES

1 PERSON PAINTS 8 WALLS IN 168 MINUTES

1 PERSON PAINTS 1 WALL IN 21 MINUTES

6 PEOPLE PAINT ONE ONE WALL IN 3.5 MINUTES

6 PEOPLE PAINT 10 WALLS IN 35 MINUTES.

HOPE THIS HELPED!!!!!!!!!

Answer 2

If 7 people can paint 8 walls in 24 minutes, then 7 people can paint 1 wall in 3 minutes. (24/3=8)

One person would take 7 times as long to paint one wall, so 1 person can paint 1 wall in 21 minutes. (7 x 3=21)

6 people can paint 1 wall in 1/6 the time (6 x as fast) 1/6 x 21/1 = 21/6 minutes

Ten wall would take 10x as long or 210/6 minutes or 105/3 = 35 minutes.
