REASONING 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.
8 ft x 5 ft

Answer 1

Explanation:

Let's find out the area of the given dimensions. In order to do that, we would just multiply 8 and 5, our given ft.

8 x 5 = 40

So if it takes 45 min for 75 feet, it takes x min for 40 feet. We can set up a ratio

`(45)/(75) = (x)/(40)`

Next we cross multiply

`75x = (45)(40) = 1800`

Now we divide by 75

`x = 24 \: minutes`
