Cleaning a car.
The way to calculate this is to figure out what fraction each does in an hour (1/20 of the job, vs. 1/25 of the job). Add the fractions together to see how much they do together in an hour, then take the reciprocal to find out how many hours it takes them.
It will take about 11.1 hours for the two of them to complete the roofing of the house.
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!
9 men taking 5 hours = 9 x 5 = 45 hour job 3 men doing a 45 hour job = 45 / 3 = 15 hours
It should take 15 electricians provided that two unlikely conditions are satisfied:all electricians work at exactly the same rate, andthe job contains no parts which are time-dependent. For example, if an instalment must be tested for 5 hours, then even infinitely many electricians will not do the job in 4 hours.

Typically, jobs are based on either a per-hour rate or a flat fee (salary). When using the per-hour basis, the longer a job takes, the more money is earned. Alternately, a flat-fee or salary based job gives one price no matter the length of time a job may take. Therefore, the longer a job takes, the less money one would make. For example, if a job is quoted at $100 and it takes 10 hours to complete, the average earnings would equal $10 per hour, subsequently, if the time to complete the job were only 2 hours, the earnings would be $50 per hour.
My somewhat educated guess would be two hours. The person who could complete the job in 3 hours could complete 2/3 of the job in two hours. The person that complete the job in 6 hours could complete 1/3 of the job in two hours. 2/3 + 1/3 = 1.
That is an 8 hour job.

Approx. 13 cents per hour. Although it depends what exactly their job was.
