Hours is a unit of time and miles is a unit of distance. Unless you introduce a speed of a given object, it is impossible to determine the relationship between hours and miles.
12 hours
Speed = distance / time. (900 miles) / (40 hours) = 22.5 miles per hour.
900 hours. Time = Distance / Speed 36,000,000 miles/ 40,000 m.p.h 900 hours.
900/60 = 15 hours
682 mi - about 10 hours 27 mins
It depends on how fast you are moving. If you are going 65 mph, the actual driving time (not including speed changes, stops or delays) would be: 13 hours 50 minutes 46 seconds.
900/75 = 12 hours
900/2.5 = 360 miles per hour
There are 0.511364 miles in 900 yards.
900 hours = 37.5 days
It depends very much on the speed at which the plane goes.
1,440 miles in two hours.
