20/12 = 5/3 hour = 12/3 hours = 1hour 40minutes
Three hours (30/10 = 3).
21.75 miles per hour
3.5 hours.
it depends on how fast you are traveling. say you were to be traveling at 10 miles per hour then you could go 80 miles. or if it were 13 then you would multiply 13 by 8. if you change your speed throughout the ride then you take your average miles per hour for every hour and add them all up.
At least 10.5 miles per hour for 3.5 miles.
The number of miles you can bike in an hour depends on your speed. On average, a person can bike around 10-15 miles per hour.
This is somehow a strange question, but I'll try to answer it. You walked 12 miles, vice versa, it's 12miles per hour.
The time it takes to bike 2 miles depends on your speed. On average, it would take about 10-15 minutes to bike 2 miles at a moderate pace of around 8-12 miles per hour.
The time it takes to bike 3 miles depends on your speed. On average, biking at a moderate pace of 12-14 miles per hour, it would take about 15-20 minutes to bike 3 miles.
The distance you can bike in an hour depends on your speed. On average, a person can bike around 10-15 miles in an hour.
Answer ; 18.65 Seconds 12miles / h = 12miles in 3600 Seconds 1 mile = 1609meters 12 miles = 12 * 1609m = 19308m 100m fits 193.08 times into 12 miles so you divide 3600 ( number of seconds in an hour) by 193.08 and you get 18.65 Seconds. One could argue that it would take a little longer, because if you are taking off from a standing start you'd have to accelerate from 0 to 12 first :-)
The speed of a bike can vary, but on average, a person riding a bike can go between 10 to 20 miles per hour.
the average American walks 3 miles per hour. that being said it would take 4 hours to walk 12 miles (3mph x 4hrs = 12miles)
34.4 / 4 = 8.6
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.
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.
4.2 miles.
