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.
to be honest it could take as long as a pice of string it just depends how fast your cycling....hope this helped you
20 minutes.
12
Well there are different lengths.A Sprint triathlon generally has 500 yd swim, 12 mile bike, and 5k run.An Olympic triathlon is 1500 m swim, 40 km bike, and 10k runA Half Ironman is 1.2 mi swim, 56 mile bike, and 13.1 mile runAn IRONMAN is 2.4 mile swim, 112 mile bike, and a marathon (26.2 miles)
yes if they can ride a bike
About 12 miles.
on your driveway
you have to be at least 12
Think about it. 12 yards is about the length of three cars parked bumper-to-bumper. You'd need to ride AMAZINGLY slow to get that distance to last one hour.
20/12 = 5/3 hour = 12/3 hours = 1hour 40minutes
A bike can travel the full 12 miles depending on the endurance of the rider.
Depends on which speed you're able to keep. A fit rider on good, flattish roads could make it in 30 minutes. An average rider on decent roads tould do it in one hour. Poor rider, poor conditions, it can take forever.
