Are you meaning how long it took to get to freedom in Ohio? It would take 8 days of continuous walking to walk there from Ohio. But, the museum said that the escaped slaves used all modes of transportation to get to freedom.
If your talking about the walk through it about a minute or two
I live in ohio
There is a video room there. It depends on how fast you see though if you have 1 hour, that would be good enough. I spent 30 minutes there. It's very nice place!
