Depends on a lot of things, how fit you are, how hard you're trying, where you're riding, what bike you're using and so on.
On easily ridden roads, a pack of racers could do it in 7-8 minutes. I'd need about 12-15. Some may need more.
There's no set answer to that question, as it would depend on how fast you're going. And that would depend on quite a lot of things, how fit you are, how hard you're trying, what kind of bike you're riding, uphill/downhill, headwind/tailwind, if you're carrying any gear, if it's a sprint or a part of a longer ride, road/offroad.... Under most circumstances it'd probably take around 6 minutes, although a real pro under ideal conditions could pull it off in around 2 minutes on level ground. I could probably get it done in around 3 minutes.
15 to 30 mins depending on how fast you walk.
Road-walking athletes can beat 15 mins easily.
depends on a lot of stuff.
but 10 mph is often used as the average pace for casual riding - so about 24 minutes.
Depends on how fast you go and the terrain.
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
