the time it takes to complete a certain job varies inversely to the number of people working on that job. If it takes 36 hrs for 7 carpenters to frame a house, how long will it take 54 carpenters to do the same job?
time=k/# of people
Need to find "k".
36 hrs = k/ 7
k=252
Equation is now t=252/#
If #=54 find "t""
t=252/54
t= 4 hr 40 min.
