Question 984019: At first two different pipes will fill a tank in 20/3 minutes, the rate that water runs though each of these pipes is changed. If one pipe, running alone, take 1 minutes less to fill the tank at the new rate, and the other pipe takes 2 minutes more to fill in the tank at the new rate, then the 2 pipes running together will fill the tank in 7 minutes. Find how much time the tank will be filled by each pipe running alone at new rates.

>>At first two different pipes will fill a tank in 20/3 minutes,

That sentence is ambiguous:

It could be taken as:

>>At first two different pipes EACH will fill a tank in 20/3 minutes,

or it could be interpreted as

>>At first two different pipes TOGETHER will fill a tank in 20/3 minutes,

We can't tell which it is.  Tell us which it is and we'll help you.
