A hose can fill a swimming pool in 12 hours. Another hose needs 6 more hours to fill the pool than the two hoses combined. How long would it take the second hose to fill the pool?

I believe it is 12, but I'm not sure.

Step-by-step explanation:

If there is 2 of the first hose, then it can fill the pool twice as fast, so thats 6 hours. (12 divided by 2 = 6).

If the second hose takes 6 hours more than that, then that would be 12 hours. (6+6=12)
