A large drain and a small drain are opened to drain a pool. The large drain can empty the pool in 7 hours. After both drains have been open for 1 hour, the large drain becomes clogged and is closed. The small drain remains open and requires 11 more hours to empty the pool. How long would it have taken the small drain, working alone, to empty the pool?
