Question

5) Naomi painted 16.5 square feet of a mural at a rate of 2 square feet per hour. Calire painted 7.5 square

feet of the mural at a rate of 4 square feet per hour. If they continue to paint at the same rates, how many
more hours will it take until Naomi and Claire have painted equal areas of the mural?

Answer 1

Answer: 4.5

Explanation:

We need to find the amount of time until Calire paints a total of 9 more square feet.

Since the difference in their rates is 2 square feet per hour, it will take 9/2 = 4.5 more hours.
