It should take 15 electricians provided that two unlikely conditions are satisfied:
It would still take six hours.
It will take about 11.1 hours for the two of them to complete the roofing of the house.
because it takes 24 hours for the earth to do a complete rotation around its axis
The hour hand takes twelve hours for a complete circle, 360 degrees. Twelve hours is 12x60 minutes = 720 minutes. If 360 degrees takes 720 minutes, 1 degree takes 720 divided by 360. 720/360 = 2 minutes.
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.
Don't worry, your son will certainly be paid. It takes about 2,000hours of on the job training and 144 hours of coursework for the length of a electricians apprenticeship.
To earn master electrician certification, individuals typically need a combination of education and work experience.

only one, but he takes 4 hours minimum and also takes 12 light bulbs.
It would still take six hours.
it takes 24 hours
a rotation in a complete circle that takes 24 hours! :)
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.
On the planet Venus, it takes 5,832 hours to complete a full rotation on the axis
It takes 3 years
It takes 24 hours for one complete cycle.
24 hours
It takes about 9 hours to complete The Saboteur.
