6.4 square feet per minute were painted
Step-by-step explanation:
First of all we have to find the area of the rectangular wall to find the wall painting per minute
Given
Length = l = 12 feet
Width = w = 8 feet
So,
[tex]Area = l*w\\= 12 * 8\\= 96\ ft^2[/tex]
Total time to paint the wall = 15 minutes
Time to paint per square feet:
[tex]= \frac{area}{time}\\=\frac{96}{15}\\= 6.4\ square\ feet\ per\ minute[/tex]
Hence,
6.4 square feet per minute were painted
