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.
it obviously depends how fast you can ride a bike and how long you can go without stopping
The time it takes to ride 8 miles on a bike depends on your speed. On average, it would take about 30-45 minutes to ride 8 miles at a moderate pace of 12-16 miles per hour.
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.
The time it takes to ride a bike from your house to the park depends on the distance between the two locations and your biking speed.
3 hours
Three hours (30/10 = 3).
20/12 = 5/3 hour = 12/3 hours = 1hour 40minutes
