It depends on the size of the house and how much is involved. Always get several estimates from different conracters and require a time frame with the bids.
It would take them 4 hours to paint the house together.
if sally can paint a house in 4 hours and john can paint the same house in 6 hours, how long will it take for them to paint the house together?
An interior painting contractor should take no more than one full day of work, or eight hours, to paint two medium sized bedrooms, unless the walls were in need of repair beforehand.
One day.
You will have to ask a Home Builder (Contractor) about how long it will take to rebuild your house. Your insurance company can usually resolve the claim portion withing 60 days. If you are having a disagreement with them then it could take longer. Your Homeowners Insurance company won't be rebuilding the house, they just pay the bill to whomever you choose to as the contractor to build the house for you.
Contractors can typically build a house within a couple of months. It varies based on the complexity of the house and the number of workers deployed to helping with the construction.
144 minutes.
Joe can paint the house in 3 hours so Joe paints 1/3 house in an hour. Similarly, Sam paint 1/5 of the house in one hour. So together (assuming no synergy) they paint 1/3 + 1/5 = 8/15 of the house in an hour. So they take 15/8 = 1 + 7/8 = 1.875 days to paint it.
Once the contractor is there, it can usually be done in a single visit, but it may take a few days to get a contractor out to your residence.
Sally does a quarter of the house in an hour, John does one-sixth, so together they would do 5/12 in an hour, thus it would take 12/5 hours ie 2 hrs 24 min in theory. In practice, because of arguments it would probably take three hours plus!
To determine how long it will take for both John and Joe to paint the house together, you can use the formula: 1/(John's rate) + 1/(Joe's rate) = 1/(Combined rate). John's rate is 1 house per 5 hours, and Joe's rate is 1 house per 3 hours. So, 1/5 + 1/3 = 1/x, where x is the combined rate. Simplifying this equation, you get 3/15 + 5/15 = 1/x, which equals 8/15 = 1/x. Therefore, it will take John and Joe approximately 1.875 hours to paint the house together.
In one hour Sally paints one quarter and John paints one sixth, between them they paint five twelfths per hour so would take 2 hours 24 minutes if they worked together. But have you ever known a male and a female to work harmoniously together? Allow at least three hours!
