If 4 people can paint fences in 5 hours how many hours will it take for 8 people to paint fences?
If 4 people can paint fences in 5 hours, this means that the rate of painting is 1 fence per person every 5 hours. Therefore, 4 people can paint 4 fences in 5 hours. To find out how many hours it will take for 8 people to paint the same number of fences, we can use the concept of inverse variation. Since the number of people has doubled (from 4 to 8), the number of hours needed will be halved. So, it will take 2.5 hours for 8 people to paint the same number of fences.
If a job takes 12 men 4 hours to complete how long should it take 15 men to complete the job?
answer:for a problem like this you have to compute how many person-hours it will take to complete the job and then it's easy to figure out the total time.so,let j = total job person-hours = 12 people * 4 hours = 48 person-hoursso, we know we need 48 person-hours to complete the entire job. so, given that we have now 15 people to complete the job,let t = total time to complete job with 15 people = 48 person-hours / 15 people = 3.2 hours, or 3 hours 12 minutestherefore, for a job that takes 12 people 4 hours, assuming there is no particular constraint on the amount done per person, the job can be done in 3 hours 12 minutes with 15 people. (for instance, although one woman can have a baby in nine months, 9 women can't have a baby in one month)previous answer:I think it'll be 1hourmy own conclusion
If it takes 15 people 8 hours to make 100 items how many hours will it take 6 people working at the same rate to make half as many items?
To solve this problem you must calculate the rate per person.15 people take 8 hours to make 100 items15p * 8h = 100i120ph = 100i1.2ph = i.So each item takes 1.2 person hours to complete (or 72 person minutes)If we need to make 50 items we need 1.2 * 50 person hours (or 72* 50 person minutes)We need 60 person hours.Since we have six people, each person needs to work 10 hours.
If it takes 3 brick layers 6 hours to build a wall how long would it take 2 brick layers to build the same wall?
I think that'd be 8 hours. 6/3 = 2 hours/worker. One less worker, 2 more hours._____________________________________________________________________nine hoursEach bricklayer can complete 1/3 of the wall in 6 hours.Two brick layers can complete 2/3 of a wall in 6 hours (2 x 1/3).To complete the other 1/3 of the wall, the two brick layers would need another 3 hours.

Two people are painting a fence one takes 3 hours to complete the job and one takes 6 hours to complete the same job how long would it take for both to complete the same job -?
Well, darling, if one person takes 3 hours and the other takes 6 hours to paint the fence, then when they join forces it will take them 2 hours to finish the job together. It's simple math, honey. Just add their individual rates of work to get the combined rate and then divide the total job by that rate. Easy peasy lemon squeezy!

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
