How long will it take her to finish the cabinets ?
She can paint 40 square feet in an hour.
210 / 40 = _______ hours
5.25 ?????
Right.
To find out how long it will take Ms. Puliafici to finish painting the cabinets, we need to calculate the total time in hours.
First, we find the number of half-hour intervals required to paint the entire cabinet area. Since Ms. Puliafici can paint 20 square feet every 1/2 hour, we divide the total cabinet area of 210 square feet by the painting rate of 20 square feet per 1/2 hour:
210 square feet / 20 square feet per 1/2 hour = 10.5 half-hour intervals
Next, we convert half-hour intervals to hours. Since there are 2 half-hours in 1 hour, we divide the number of half-hour intervals by 2:
10.5 half-hour intervals / 2 = 5.25 hours
Therefore, it will take Ms. Puliafici approximately 5.25 hours to finish painting the cabinets.
