distance=rate*time
Jill can paint 1 house in 5 hours. 1=r*5 r=1/5 houses/hour
Tom can paint 1 house in 4 hours. 1=r*4 r=1/4 houses/hour
1 house = 1/5*x+1/4*x
1=(4x+5x)/20
20=9x
x= 2.2 repeating hours (2 hours, 13 minutes, 20 seconds)

Delbert can paint a fence by himself in 11 hours and Dorothy can paint the same fence in 12 hours How long will it take them to paint the fence if they work together?
Delbert can paint the fence in 11 hours so in 1 hour Delbert paints 1/11 of a fence. Similarly, in 1 hour Dorothy paints 1/12 of a fence. So together, in 1 hour they paint 1/11 + 1/12 = 12/132 + 11/132 = 23/132 of a fence. So to paint the fence together they would need 1 / (23/132) = 132/23 hours = 5.74 hours
Masie can paint a room in 5 hours.Florence can paint the same room in 6 hours If they paint together?
Assuming that there is no synergy, nor time wasted when the two of them start chatting, M paints 0.2 rooms per hour F paints 0.166.. rooms per hour so M + F paint 0.366... rooms per hour So it takes them 1/0.366... = 2.7272... hours
If sally can paint a house in four hours and john can paint the same house in 6 hours how long will it take both of them to paint the house?
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.

If Joe can paint a house in 3 hours and Sam can paint the same house in 5 hours how long does it take for them to do it together?
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.

If john can paint a house in 5 hours and joe can paint a house in 3 hours how long will it take for both of them to paint the house?
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.

How many Gallons of paint needed to paint the U.S White House?
I work for Sherwin Williams paints and from what I understand it is our paints that paint The White House. The paint is a special mix. Everyone who comes in contact with the paint has to go through a background check.

If Sarah paints a room in 4 hours and sam paints the same room is 6 hours how long will it take for both to paint one room?
We know that Sally can paint the house by herself in four hours. Put another way, she can paint 1/4 of the house in an hour. Using similar logic, we know John paints at a rate of just 1/6 of a house per hour. If we convert those fractions to fractions with a common denominator, we have 3/12 of a house for Sally and 2/12 of a house for John, so together they can paint at a rate of 5/12 of a house per hour. But that is not yet the answer to the question. If you take the reciprocal of 5/12 houses per hour, you get 12/5 hours per house. That equals 2.4 hours per house. Converting to hours and minutes, you get 2 hours, 24 minutes -- because 0.4 hours equals 24 minutes. (0.4 hours x 60 minutes/hour = 24 minutes.) Algebra OR Above answer of this question is right.but we can also define it some other way, in percentage. May be this solution make esay for some friends to understand.Silly tooks 4 hors to paint 100 % (full house).Jhon tooks 6 hours to paint 100 % (Full house).In an hoursilly can paint 25 % of house & Jhon can paint 16.66 % of house, so they both can paint 41.66 percent of house in an hour.so, if we divide (total required work) / (work they can do in an Hour)= 100 / 41.66we I'll get the total time to paint complete house.ANSWERS IS : 2.4 Hours or 2 hours 24 minutes.
