It means it takes the person over three hours to get to work (and possibly the same amount of time to get home).

I don't understand what this sentence means.
At the moment I commute for over three hours, but I'm intending to move closer to my work in the next few months.
The bold part doesn't make any sense for me, but it does for native speaker.
I've not found an appropritate meaning in the dictionary that's why I'm asking.
I'll be grateful if you exaplain it to me.
Please, correct all my mistakes. I should know English perfectly and if you show me my mistakes I will achieve my dream a little bit faster. A lot of thanks.

I would say that it's ambiguous. It could mean it takes three hours to get to work and another three hours to get back. It could also mean that it takes ninety minutes to get to work and another ninety minutes to get back (a total of three hours).
