A large pipe can fill a swimming pool in 10 hours, while a smaller pipe can empty the pool in 15 hours. How long would it take to fill the pool if both pipes were accidentally left open?
-----------------
1/10 of the pool per hour added
1/15 of the pool per hour drained
---
1/10 - 1/15 = 1/30 gained per hour
---> 30 hours
