If you want 1btc you need to make 0.142 or something btc per day
so over 0.005 an hour....
Also btc is $730 do you think it is going to be that easy to make that kind of money ?
People go to school/work, go to sleep, eat, take a bath, etc. Most people only have 8 hours maximum to spend in front of the computer in a day. That would divide your calculations into three since 24/8 = 3. Thus, the maximum earning you can get from faucet sites is just around 0.01BTC. I don't think that's worth doing. There's a lot of better ways you could've spent all those time.
