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.)

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.
John can paint 1/6 of a house per hour.
Let's say the answer is t hours for the total job.
Then (1/4)t + (1/6)t = 1
(1/4 + 1/6)t = 1
(6/24 + 4/24)t = 1
(10/24)t = 1
t = 24/10 hours = 2.4 hours
AnswerIf Sally can paint a house in 4 hours, then she can paint 1/4 of a house in 1 hour.If John can paint a house in 6 hours, then he can paint 1/6 of a house in 1 hour.
Let x be the number of hours it would take them to paint the house.
Working together, they can paint 1/x of the house in one hour, so
1/4 + 1/6 = 1/x
Multiply by LCD, so 12x (1/4 + 1/6 =1/x)
3x + 2x = 12
5x = 12
x=2.4 hours. Also, 40 % of 60 minutes is 24 minutes.
Final answer = 2 hours and 24 minutes.
AnswerThe equation is this:Multiply both sides by the LCD which is 12x:
= 2.4 hours

If Sally can paint a house in 4 hours, and John can paint the same house in 6 hour, how long will it take for both of them to paint the house together?
It takes 8 days for 2 painters to paint 4 houses.
P.S: Assuming all the houses are identical in size and shape and the ability of the painters aswell. - Pradeep Reddy
Five hours.
Yes, as long as they are both the same base, you can mix many paints.
Yes, they make both Sears Weatherbeater and Sears Easy Living paints.
The short answer is yes. Acrylic paints can be applied to both canvases and walls, with either a natural or manufactured sponge to get many different finishes.
Yes, since both are water based paints you can mix the to together.
It's a matter of personal preference. What works great for one person isn't always how it is going to work for another. That's why there are so many different brands. Same is true for cars ... impossible to compare by brand names.
The word paint is both a a verb (paint, paints, painting, painted) and a noun (paint, paints). Example sentences:verb: We plan to paint the baby's room yellow and cream.noun: The paint we want is on sale at Murphy's Hardware.
Latex and acrylic (both water-based paints) do come in a semi-gloss finish.
If it is just one kind of paint then its like the word water, no plural just a measurement or unit (5 gallons of water, 3 buckets of paint). If it is different KINDS of paint (different colors or types of paints like latex as opposed to oil) the plural is paints ("I brought my paints with me for art class")
Yes. Both lead-based and zinc-based paints are toxic to hamsters.
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.
Yes, as long as they are both the same base, you can mix many paints.
There are concrete paints available. A three step epoxy paint give a very attractive finish. Both products are available at Lowe's or Home Depot
Yes, they make both Sears Weatherbeater and Sears Easy Living paints.
Both the water based paints and the oil based paints can be used on the concrete fountains. However, the oil-based pains are the best as they cannot be washed easily unlike the water based paints.
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.
It would take them 4 hours to paint the house together.
