Question

Naomi and Claire are painting a mural. Naomi paints 2 square feet per hour and has already painted 16.5 square feet.
Claire paints 4 square feet per hour and has already painted 7.5 square feet.
How many more hours will it take for Naomi and Claire to paint an equal total number of square feet?

Answer 1

4.5 hours We can sum up the information in the question with two equations: y = 2x + 16.5 y = 4x + 7.5 Where y represents the total area painted by each person and x represents the time. These equations are in the form y = mx + b where m is the rate and b is the value at x = 0.
