Suppose that the time it takes to do a job is inversely proportional to the number of workers. That is, the more workers on the job the less time required to complete the job. If it takes 3 workers 16 days to finish a job, how long will it take 8 workers?

6 days

Question

Suppose that the time it takes to do a job is inversely proportional to the number of workers. That is, the more workers on the job the less time required to complete the job. If it takes 3 workers 16 days to finish a job, how long will it take 8 workers?
 	
	6 days
	10 days
	2 days
	14 days

anonymous · Answer

time = k (constant of proportionality) x no.of workers
16 days = k x 3
k= 16/3 
time = k x 8
time = 16/3 x 8
