a painter said it would take 1 person 120 hours to paint his house how many days would it take 4 people 6 hours a day

You can divide the total hours (120) by the daily hours (6) to get the total days

120/6 = 20 days

Then you would divide the total days (20) by the number of people (4) to get the total amount of people to work 6 hours per day to complete the job

20/4 = 5 days

So, it will take 4 people 5 days to work a total of 120 hours to paint the house.

To check this, you would calculate:

4 people x 6 hours per day x 5 days = 120 total hours

it would take 5 days for 4 people to paint the house because you would divide 4 by 120 and get 30 then divide that by 6 to get you 5
