<pre>
One pipe can fill a tank in 20 minutes, while	
another takes 30 minutes to fill the same tank. How long would it take the two pipes together to fill the tank?

Answer is RIGHT HERE, below.....Question 45662:
Hi again,
I need some assistance with this mixture problem:
It takes a pipe 10 minutes less than another one to fill a tank of water. <font color = red><font size = 3><b>Both pipes together can fill the tank
in 12 minutes.</font></font></b> How long will it take each one to fill the tank separately?
I am having trouble on how to start setting the equation up.
Thanks again,
Lou</pre>
