It takes approx 9 minutes and 28 seconds.
It would take about 4 hours and 40 minutes.
15 miles would take 22 minutes 30 seconds at 40 mph.
28 kph = 17.4 mph
mph means miles per hour just record how long it takes to go one mile. If you walk for a mile and it takes 30 minutes then your speed for that mile was 2 mph. If you walk for a mile and it takes 15 minutes then your speed for that mile was 4 mph. ... lets do a crazy one... If you walk for a mile and it takes 23 minutes and 30 seconds then your speed for that mile was 2.55 mph. The math is simple. If your time is in minutes just take 60 minutes and divide into that the total amount of minutes you took to walk a mile. So the calculations for the three examples would be... 60 / 30 = 2 mph 60 / 15 = 4 mph 60 / 23.5 = 2.55 mph (23 minutes and 30 seconds is the same as 23 and a half minutes)
1.15 miles per hour is approximately to 1.85 kilometers per hour There are further decimal places I do not care to type out and you likely do not care to know.
One hour
It would take 15 hours to bike 225 miles at a speed of 15 mph.
Just under 15 minutes.
60/15 = 4 hours
8 minutes.
15 minutes.
45 minutes.
22.5 minutes.
450 mi / 30 MPH = 15 hours
About 9 seconds.
No. It would take about 15 minutes at 65 mph
26 minutes 15 seconds.
