Question

Naomi and Claire are painting a mural. Naomi paints 2 square feet per hour and has already painted 16.5 square feet.

Answer 1

Answer:

4.5 hours

Step-by-step explanation:

let t be the time elapsed

Therefore, we can set up a system of equations and solve accordingly

2t + 16.5 = 4t + 7.5

2t = 9

t = 4.5 hours more till they paint the same amount in square feet
