If akayla painted 1/3 of a wall in 20 minutes how long will it take her to paint 4 walls

240 minute or 4 hours

Step-by-step explanation:

We can use a ratio to solve

1/3 wall           4 walls

 =

20 minutes      x minutes

Using cross products

1/3 x = 20 *4

1/3 x = 80

Multiple each side by 3

1/3 x* 3 = 80*3

x = 240 minutes

Divide each side by 60 to change to hours

x = 240/60

x = 4 hours
