Every minute 1/60 of the pond comes in the inlet pipe and 1/80 of the full pond goes out.  So you find the difference:  \n\n(1/60)x - (1/80)x = (8/480)x-(6/480)x=(2/480)x= 1/240x\n\nwhere x is the amount of water that would fill the pond\n\n1/240 of the amount of water to fill the pond comes in every minute.  It should take 240 minutes for the pond to fill up.

At most shouldn't it take only 13 minutes?  If 1 & 2 cross together, then they will take 3 minutes, and if 3 & 4 cross together, they will need 10 minutes.  10 + 3 = 13.\n\nMaybe I don't really understand the question??

Use the binomial.  I've already shown you how in a previous question.  And you already know that you need to use it.
