That depends on how many men there are.
If there is 1 man, then he does 7,000,000 man-hours of work in 7,000,000 hours,
or about 798 years of continuous work.
If there are 1,000 men, then they do 7,000,000 man-hours of work in 7,000 hours,
or about 292 days of continuous work.
If there are 100,000 men, then they do 7,000,000 man-hours of work in 70 hours,
or about 2.917 days of continuous work.
The problem we have with this question is that a "man-hour" is not a unit of time.
Taking into consideration that each man works an 8 hour work day: (4 x 8) x 48 = 1536 man hours to complete the job for 4 men *** (Men x Man hours per day) x Days Worked = Total Job Man Hours *** 1536 / (3 x 8) = 64 days for 3 men to complete the same job *** Total Job Man Hours / (Men x Man Hours per day) = Days until Job Completion***
3472 days, 5 hours, 21 minutes (approximately)
I doubt even 1
Since we are given no information to the contrary, the following discussion assumes that all men are created equal, and every worker accomplishes the same amount of work in the same amount of time. Since 8 workers can build a cabin in 60 hours, the job comprises (8 man) times (60 hours) = 480 man-hours of labor. That doesn't change. Now however, 480 man-hours of labor must be completed in 32 hours. The number of workers required to accomplish this is (480 man-hours) divided by (32 hours) = 15 man.
Safe man hours is the number of hours worked minus the number of hours lost due to unsafe work or lost work due to an incident. This should get you the answer to total safe man hours.
Taking into consideration that each man works an 8 hour work day: (4 x 8) x 48 = 1536 man hours to complete the job for 4 men *** (Men x Man hours per day) x Days Worked = Total Job Man Hours *** 1536 / (3 x 8) = 64 days for 3 men to complete the same job *** Total Job Man Hours / (Men x Man Hours per day) = Days until Job Completion***
The equivalent to 120 hours is 5 days. 120 divided by 24 =5
3472 days, 5 hours, 21 minutes (approximately)
