Distance = Speed*Time = 56*3 = 168 miles.
if you are driving then you would go about an avaerage of 60 miles per hour. if you were going this fast then going 281miles it would take you 4 hours and 41 minutes.
640 miles would be 8 hours exactly. 639 is 7.9875
20.4 hours
The answer is incalculable because hours is a unit of time and miles is a unit of distance. If you are asking how many hours it would take you to drive 306 miles, you would have to include how fast you are going.
800 miles / 16 miles per hour = 50 hours
It would depend on how fast you're going--if you're going an average of 50 mph, then it would take approximately 26 hours for 1300 miles.
6 hours
162.5 miles
Fly's fly at an average of 4.5 mph. So in three hours, they would fly about 13.5 miles.
It would take 1.5 hours.
7 hours, 38 minutes, 46.15 seconds
The average person could run 9 to 12 miles in three hours. Most people could not run for three hours, so many would walk portions of this challenge.
