To find out how many square feet the painter can paint in 7 hours, we need to set up a proportion.
The painting rate is given: 375 square feet in 3 hours.
We can set up the proportion as follows:
375 square feet / 3 hours = ? square feet / 7 hours
To find the value of ?, we can cross-multiply and solve for it:
375 square feet * 7 hours = 3 hours * ? square feet
2625 square feet = 3 hours * ? square feet
Divide both sides of the equation by 3 to solve for ?:
2625 square feet / 3 = 3 hours * ? square feet / 3
875 square feet = ? square feet
Therefore, the painter can paint 875 square feet in 7 hours.
A painter can paint 375 square feet in 3 hours. At this rate, how many square feet can he paint in 7 hours?(1 point)
