Less than two hours.
It would take them 4 hours to paint the house together.
~1.9 hours
It will take about 11.1 hours for the two of them to complete the roofing of the house.
You don't need a formula. You need to understand where the answer comes from. If you understand where the answer comes from, you can write your own formula. If you don't, then a formula can be dangerous in your hands. -- Sally can paint 1/4 of the house in an hour. -- John can paint 1/6 of the same house in an hour. -- If they work together, then can paint (1/4 + 1/6) = 5/12 of the house in an hour. -- If they paint 5/12 of the house in an hour, then it takes them 12/5 hours to finish the job, or 2.4 hours, or 2hours 24minutes. Well, OK. Here's the formula: S = number of hours it takes Sally J = number of hours it takes John Number of hours it takes them working together = 1 / (1/S + 1/J)
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!
The way you calculate this (assuming that both work at constant speed) is:* Calculate what part of the house each person can paint in an hour. * Add both fractions together, to calculate what part of the house you can paint together. * Take the reciprocal of this last result, to calculate the number of hours.

Yes, more than one family can live together in a Section 8 house. For example, a single person is considered a family of one and thus, can share a house with another family of one.

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?
yes
It will take Sally and John 2.4 hours to paint the house together. This can be calculated by using the formula 1/4 + 1/6 = 5/12, which means they can paint 5/12 of the house per hour together. To find the time it takes to paint the whole house, you can divide 1 (the whole house) by 5/12, which equals 2.4 hours.

the house needs to be almost the size of a penny.... or a person who has a crappy house and there is an another or... the other or is that the person is a nice man and does not want much money,
