If we say one painter covers one unit in one hour, then 8 painters cover 8 units in an hour and 48 units in 6 hours. The gymnasium therefore has 48 units of wall. 12 painters cover 12 units in an hour and so will take only 4 hours to cover the 48 units
4hours
6 x 8=48 person hours
Multiply 3 and 5 to get a Least Common Multiple. 15. So you find how many rooms can Alvin paint in 15 hours (5 rooms). Same with Bernie (3 rooms). That means they can paint 8 rooms in 15 hours. Since you want to find "how long it would take," you flip the rate over. In 15 hours they can paint 8 rooms. Reduce if you want, 15/8= 1.875 hour to paint one room.
One hour is saved. The three guys need two more hours to finish. If three more guys help them, it will cut the time in half. 3 guys * 5 hours = 1 house painted guy * hour = 1 hour of labor So it would take 15 hours of labor to paint a house. We need to assume houses take the same time to paint and each guy works at the same rate. 3 guys * 3 hours = 9 hours of labor 9 hours of labor + (3+3) guys * x hours = 15 hours of labor 9 + 6x = 15 x=1 Total time = 3 hours of 3man + 1 hour of 6 man = 4 hours time saved = 5-4 = 1 hour

Time how long it takes to paint 10 sq ft. To paint 2000 sq ft would therefore take 200 times as long. With a roller on a prepared wall and a competent painter then 10 sq ft could be painted in less than 1 minute so 2000 sq ft would take 3 -4 hours.
6 x 8=48 person hours
It would take them 4 hours to paint the house together.
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)
it takes about 3 and a half hours to dry in a living room
It takes approximately 2 hours 37 minutes.
1.5 hours + 2 hours = 3.5 hours So 3.5 hours in total!

8 hours...think of it as a ratio: 5/10=4/?
between 24-48 hours depending on 1, the quality of the gloss, and 2, how thick you apply it. Have fun! Its a crap job!!!
Work out how long on average it takes to paint it and how much paint you used.(T X HW) + (PC X VP) = how much to charge.Where:T is the time it takes you to paint 1ft2 in hours. (10 mins= 0.167, 15 mins=0.25)HW is how much you think you should make per hour.PC is the paint cost per unit volume.VP is the volume of paint used.
No, the word 'paint' is a noun (paint, paints) and a verb (paint, paints, painting, painted).A pronoun is a word that takes the place of a noun in a sentence.The pronoun that takes the place of the noun 'paint' is it,.Examples:That paint is the perfect color. (noun)We can paint the hallway first. (verb)That paint is the perfect color. It is a good brand, also. (the pronoun 'it' takes the place of the noun 'paint' in the second sentence)
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.
