It takes 0.15625 minutes to paint 1 square feet
Solution:
Given that, I can paint 96 sq ft in 15 minutes
To find: Time taken to paint 1 square feet
From given,
96 square feet is painted in 15 minutes
Let "x" be the time taken to paint 1 square feet
Then, we can say,
96 square feet = 15 minutes
1 square feet = x minutes
This forms a proportion and we can solve the sum by cross multiplying
[tex]96 \times x = 15 \times 1\\\\x = \frac{15}{96}\\\\x = 0.15625[/tex]
Thus it takes 0.15625 minutes to paint 1 square feet
