sigfried can paint a house in 5hrs. stephanie can do it in 4hours how long will it take the two working together
Answer (1)
Answer:2.22 HoursStep-by-step explanation:1. Siegfried paints a house in five hours, so he paints one-fifth of the house in one hour. Stephanie paints a house in four hours, so she paints one-fourth of the house in one hour.2. Combine their painting rates. Together, in one hour, they paint one-fifth plus one-fourth of the house. To add these, convert them to a common unit. One-fifth is equivalent to four-twentieths, and one-fourth is equivalent to five-twentieths. Together, they paint nine-twentieths of the house in one hour.3. To paint the entire house, divide one house by the combined rate of nine-twentieths of a house per hour. This results in twenty divided by nine hours.4. The result is approximately two hours and thirteen minutes.So, it will take them about two hours and thirteen minutes to paint the house together.
