This is a form of work problem- like when you know how long
it takes for person a to do a job and person b to do a job,
how long does it take when they work together?
For this problem,
(pipe A's rate of filling pool)+(pipe B's rate of filling pool)
= (rate of A and B together filling pool)
in other words,
(1 pool/6 hrs) + (1 pool/12 hrs) = (1 pool/x hrs)

multiply both sides by

hrs answer
It takes 4 hrs to fill the pool when both pipes are left open
check answer

OK
