Time=distance over time (t=d/s). So, 45 / 70 = 0.643 hours. To get this into minute's, multiply the 0.643 hours by 60 (60 minutes in an hour). Which equals 38.57 minutes.

There's really no definite answer to that. A group of fit road riders and good, flat(ish) road conditions - less than 3 hours. Me, on my own, same conditions - 4-5 hours. Poorer conditions, maybe less dedicated riders - say 6 hours. Really difficult conditions - 10 hours.

Since a stationary bike doesn't move, there's no way it can travel 20 miles. Now, if you're asking how long it would take to ride twenty miles on a bicycle, it depends on speed, wind, and other factors. Typically a bike maximum speed is about 20 miles per hour. So it would take about an hour to ride 20 miles on a REGULAR moving bicycle.
