It will take about 11.1 hours for the two of them to complete the roofing of the house.
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.
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.
The usual working day is 8 hours (9 including breaks) (if you're lucky to get a job with the usual hours, usually public service here in ireland anyway). 8 hrs is 480 minutes.

As many as are available to be worked. Anything over 40 hours at one job requires overtime pay, but you can work as many hours as you're capable of working.

5 and one sevenths
the answer is 5 hours because when we add the two secretaries the first one will be done typing in 6 hours and the other is 4 hours so if we add the two of them so 6 hours plus 4 hours is equals to 10 hours and divide it how many people will do the job so 2 people the first secretary and the second secretary. so 10 divided by 2 is 5 so the answer is 5 hours.
