math problem....?
The time it takes to set up a circus tent varies inversely with the number E of elephants used. If 12 elephants can set up a tent in 4 hours, how long will it take 3 elephants?

Time = Constant / Elephants
Constant = 12 elephants * 4 hours = 48 elephant hours
for 3 elephants
Time =48 / 3 = 16 hours

although #1 seems right, when you look at the problem, it doesnt make sense: if it takes 12 elephants to work in 4 hours, why would it take less elephants to set up a tent in less hours? it seems that it would take 3 elephants 16 hours to do the work (quadruple the hours it would take 12 elephants) I think #2 is right--16 hours...

16 Hours
1/4 of amount of elephants, so each elephant does 4 times more work. 4 hours times 4 is 16 hours
