Depends on a lot of things. A fit rider can do 20 MPH for several hours under reasonably easy riding conditions, so with a few pit stops you'd might be able to pull it off in just under two hours.
Or you may need the double, if you're not as fit, if your bike is poor or if riding conditions are poor.
It would depend entirely on riding speed, which would be dependent on a whole range of things. Bike type, riding surface, fitness, level of exertion and more. A decent road rider on the flat would be able to do it in 30 minutes, an elite track rider could pull it off on 20-something minutes. Most regular riders would do it in less than one hour, assuming a reasonably flat road.

Or you may need the double, if riding conditions are poor, if the bike isn't working well, or if you simply isn't as fit.
Depends on fitness level, how hard you're trying, what bike you're on and general riding conditions. There are those who could do it in about 90 minutes in good conditions. I could probably do it in a bit more than two hours. Many would need about three hours, and some would be in around 4 hours.
Depends on what average speed you're able to maintain. Me, on roads, mainly flat, I'd be done in about two hours.
it obviously depends how fast you can ride a bike and how long you can go without stopping
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.
20 minutes.
if your speed is 4 miles per hour it takes an hour,at 8mph it takes 30 minutes.
I presume you mean how long will it take for a 12 miles bike ride. It depends on how fast you can bike, if it's uphill or downhill. The average is between 8-13 mph for most people to bike on a 10-speed on the whole. By that measurement, it could take 50-90 minutes or so on the average.
26 divided by 8 equals 3.25 hours or 3 hours and 15 minutes
A: 9 hours.
It cannot be done. To ride a bike around the earth, the continents would need to be connected, or the bike would need a really long bridge across the ocean.
3 hours
Three hours (30/10 = 3).
20/12 = 5/3 hour = 12/3 hours = 1hour 40minutes
Lassen uns rad fahren = let us take a bike ride.
