A painting crew paints at a rate of 1 2 square foot per second. If the area of the walls in a house are 4500 square feet, how long does it take them to finish painting the house?
For this case we have the following equation: t = A / v Where, t: time A: area v: speed Substituting values we have: t = 4500 / (1/2) t = 9000 seconds Answer: It will take them to finish painting the house about: t = 9000 seconds
