Depending on how fast you're going, 15 miles would take one hour if you're going 15 miles per hour. If you're going 10 mph, 15 miles would take 1 1/2 hours. If you're going 20 mph, 15 miles would take 45 minutes.
it depends on how strong you are, what type of bike you are riding, what the surface is like, whether there are gradients, wind direction, weather, traffic etc. On my racing bike at full speed with zero wind I generally cover a completely flat 5 miles on the road in a little over 15 minutes, but on a mountain bike that would probably be more like 24 minutes. Add in a hill or two and off-road terrain and you are probably talking about 30 minutes.
It depends on the kind of bike, the gear you are in, the circumfrace of the tires, and how fast you are peddling. Although, with all of the factors at average, about 10-20 minutes.
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 15 minutes, although a good rider under ideal conditions could pull it off in around 8 minutes on level ground. I could probably get it done in around 11 minutes.
To find an average speed you must do distance divided by time. Or speed times time equals distance. In this case you would do 15 divided by 30=...
By the way we learned this in Science Class
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 8-10 hours continuous riding.
Unless you're a seasoned rider this would be rather uncomfortable and quite demanding, you'd might want to split it into two stages with an overnight stay inbetween.
That would be easily doable assuming you're travelling light.
If you need to carry camping gear or use poorer roads it'll still be doable, but a bit harder.
It can be done in 35 minutes if you are in shape, but if you are not it should take about 45 minutes to an hour.
If you 'bike' at an average of 10 miles per hour, 10 miles will take one hour assuming you do not stop for a break on route.
30 min if going steady pace.
That depends on your speed.
3.5 hours.
About 20 minutes.
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 min: 60 mph = 1 mpmin
It will take one hour to travel 30 miles.
3 hours
Three hours (30/10 = 3).
The number of hours it will take to travel 308 miles is(308)/(your average speed, in miles per hour)
it obviously depends how fast you can ride a bike and how long you can go without stopping
3.5 hours
About 15 minutes
