20/12 = 5/3 hour = 12/3 hours = 1hour 40minutes
Three hours (30/10 = 3).

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.
This is somehow a strange question, but I'll try to answer it. You walked 12 miles, vice versa, it's 12miles per 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 :-)
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 average American walks 3 miles per hour. that being said it would take 4 hours to walk 12 miles (3mph x 4hrs = 12miles)
4.2 miles.
Three hours (30/10 = 3).
9 miles per hour
21.75 miles per hour
Yes, Jennifer can be home in an hour. This is because she expects to wait only 30 minutes for the repair, and then she will ride her bike home. The bike shop is only 1.5 miles from her house, so she will be able to make the trip in a reasonable amount of time.
The answer is one hour and six minutes and 30 seconds.
The 208cc mini bike can travel at 40 miles per hour.
