A painter can paint 375 square feet in 3 hours. At this rate, how many square feet can he paint in 7 hours?
To find the square footage painted per hour, divide the total square footage by the number of hours: 375 sq ft / 3 hours = <<375/3=125>>125 sq ft/hr
The painter can paint 125 sq ft/hr x 7 hours = <<125*7=875>>875 square feet in 7 hours. Answer: \boxed{875}.
To calculate the number of square feet the painter can paint in 7 hours, we can use a proportion.
First, let's set up the proportion:
3 hours = 375 square feet
7 hours = x square feet
Now, we can cross multiply to solve for x:
3 * x = 7 * 375
This simplifies to:
3x = 2625
Next, divide both sides of the equation by 3:
x = 2625 / 3
Simplifying further:
x = 875
Therefore, the painter can paint 875 square feet in 7 hours.
To find out how many square feet the painter can paint in 7 hours, we can use a proportion.
Let's set up a proportion:
375 square feet in 3 hours = x square feet in 7 hours
To solve for x, we can use the following cross-multiplication method:
375 * 7 = 3 * x
Divide both sides of the equation by 3:
2625 = 3x
Now, divide both sides by 3 to isolate x:
x = 2625 / 3
Calculating the result:
x = 875
Therefore, the painter can paint 875 square feet in 7 hours.
Using the proportion method allows us to solve similar problems where the given information is in a different ratio or measurement.
