Wow! I've only written 6 hubs, all on content that I'm very familiar with so little to no research, and each one of them has taken me about 3 or 4 hours. I didn't realize I was so slow!
If it's personal about me or my family, about an hour. If it's sports or work related, about 3-4 hours. I hope that helps.
In my case, i´m only beginning. But i´m spending about 2 hours for one hub. I´m trying to write good hubs so it takes time.
In my case it takes me less than one hour. But then again, it depends on how much research is necessary in order for it to be factual and accurate. But even with a lot of extensive research I get it done rather quickly.
I am not sure why; I guess when the germ of creativity is there, I'm fired up ready to go and the work seems to come effortlessly.
So I would have to say an hour or less. :).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
