Homework Statement
"A tank can be filled in 6 hours using 2 pipes. The larger pipe alone would fill it 5 hours sooner than the smaller pipe alone. How long would each pipe alone take?"
Homework Equations
I know it involves a quadratic not sure on the rest... I can't see how to do with a quadratic i mean.
The Attempt at a Solution
assume a is the big pipe and b is the small
A+B=6
A=B+5 solved them to get a=11/2hours and b=1/2, i can see that's not right. i said that a was the bigger one and my answer says that its not?
