It takes 3600 person hours to complete a project. How many weeks will it take a team of 15 people to complete the job if each person works 8 hours, 5 days a week

lets say one hour of work is x units of work

then it will take 3600 x to complete the project

then each person gets 3600 / 15 = 240 x

each person gets 240 hours

if each person does 8 x per day,

there will be 30 days needed

30 days / 5 days = 6 weeks
