If it takes 4 workers 3 days to frame 2 houses, how many days will it take 3 workers to frame 5 houses?

Rate = 2 houses / (4 workers * 3 days)\nRate = 1/6 house per worker per day.\n\n3 workers * n days * 1/6 house/worker = 5 houses\nn = 5 * 6 / 3\nn = 30 / 3\nn = 10 days

My calculation says it's about 4.35 minutes.

2 hours\n\nedit: WHY would it be more than 3 hours??? if the brickie does it alone it would be 3 hours max. why say 4.5 hours?? :(

Sam takes 4 days to complete the job\nTherefore,in one day he completes 1/4 of the job\nSimilarly,Lisa completes 1/6 in a day and Tom 1/2 in a day.\nTherefore,in one day they all together complete\n1/4 + 1/6 + 1/2\nwhich equals (3+2+6)/12 = 11/12 of the work in one day\nTherefore together they take (1)/(11/12) days= 12/11 days

A couple days,\nmaybe even five, if they're behind schedule\nit depends on where you live

woodyy....\n\nThis is an extension of the idea of a rate problem.\n\nd = rt\n\nBut instead we have 3 guys painting a wall in an hour and a half. How would you convert that sentence into math?\n\n(3 guys)(1.5 hrs) = 1 wall\n\nLoosely speaking.....the guys are the 'rate' (r), the 1 hr is obviously time (t), and the wall is the 'distance'.\n\nMost things in math and physics DO make sense.\n\nThink about this....if 3 guys can paint one wall in one and a half hours, and the equation is written as I wrote it...namely:\n\n(3 guys)(1.5 hrs) = 1 wall\n\nThen to add more guys, more walls, more time...whatever....these things, arguably have to be proportional, and that's the key to setting this up, and that's what you have to learn how to do.\n\n(3 guys)(1.5 hrs) = 1 wall\n\n==> (3 guys)(1.5 hrs)/1 wall\n\nWhat's this have to be equal to?\n\n9 guys painting 6 walls....in some amount of time.\n\n==> (9 guys)(x hrs) = 6 walls\n\n==> (9 guys)(x hrs)/6 wall\n\nRight?\n\nThese are proportional, so that means you can set them equal to each other.\n\n(3 guys)(1.5 hrs)/1 wall = (9 guys)(x hrs)/6 wall\n\nNow, solve for the infamous 'x'.\n\nI'm gonna get rid of the units so it's easier to type and easier for you to read.\n\n(3)(1.5)/1 = (9)(x)/6\n\n==> 3*1.5 = 9x/6\n\n==> x = 3*1.5*6/9\n\n==> x = 3....and the units are hours.\n\nSo, it takes 3 hours for 9 guys to paint 6 walls.

2 quick: 5 min\n2 long: 2 Days

its around 3-4 days i think.

"Building schedule" Are you constructing a fire station?  Question not stated well at all...  Sry

it depends on the insurance. but usually 5 days.

let m = the amount of work 1 man can complete in1 day, let b = the amount of work one boy can do in a day.\n\n42m + 56b = 1\n40m + 60b = 1\n\n1680m + 2240b = 40\n1680m + 2520b = 42\n\n280b = 2\nb = 1/140.\n\n42m + 2/5=1   [56/140=2/5]\n42m = 3/5\nm = 1/70.\n\nSo one man can do 1/70 of the job in 1 day, so it takes him 70 days to do the whole job.\n\nSo the answer is 70 days.\n\nAlso, my answer is correct, not 22 as many people are saying. If it were 22, then 3 men could complete the job alone in just 7 1/3 days. But even working with 4 boys it takes them 14!

5, 10 or 15 days usually depends on the state and or county or city,\n\nhere it's 10 days thats working days.

2-3 days I would think:)

4 walls -> 5m x 2.5m x 4 = 50 sq.m\nRoof    -> 5m x 5m       = 25 sq.m  total 75 sq.m\n\nLess for 1 door -> 0.9m x 1.8m = 1.62 sq.m\nless for 2 windows 1.2m x 1m x 2 = 2.4 sq.m total 4.02 sq.m\n\nArea to be painted 75-4.02 = 70.98 sq.m\nNow just multiply with the rate

usually 3-5 working days...don't count the weekend days....

It can be assumed that the relationship between these variables is as follows:\n\nh = mdk\n\nwhere:\n\nLet m = how many men are building houses\nLet h = how many houses are built\nLet d = number of days elapsed\nLet k = a constant\n\nThat is to say; the number of houses built is dependant on the number of men building and number of days elapsed.\n\nWe can plug in our values and figure out our constant:\n\n1.5 = (1.5 * 1.5) k\n1.5 = 2.25 k\nk = 1.5 / 2.25\nk = 2/3 (or .666666666 repeating)\n\nNow we have an equation to figure out the question:\n\nh = mdk\n\n1 = 1 * d * (2/3)\n\n3/2 = d\n\nIt would still take a day and a half for 1 man to build 1 house.

The workshop ran for (5) days over the course of (one month).\nAlthough "a number of days" doesn't really imply consecutive---but for many workshops there's an advantage in the "breathing-time" between sessions so I'd go with the "over the course of" option.
