You can paint 75 square feet of a surface every 45 minutes. Determine how long it takes you to paint a wall with the given dimensions.8ft X 5ft
+592 \(\frac{75}{45} = \frac{100}{60}\). This means you can paint 100 square feet every 60 minutes. 8ft x 5ft = 40 square feet
\(\frac{40}{x} = \frac{100}{60}\)
\(2400 = 100x \)
\(x = 24\)
This means it will take you 24 minutes to paint an 8ft by 5ft wall :)
