The time to complete a building project is inversely proportional to the number of people working on the job. It takes 30 days for 6 workers to complete the job. If they need to complete the job in 20 days, how many workers will they need?
30 days 6 workers
20 days x workers
x/6 = 30/20
x= 6*30/20
x= 9 workers
