800/7 , getting on for 115 hours
That depends on the speed of travel.
It would be 800 years.
The answer will depend if you mean 800 nautical miles (as would often be used in relation to knots) or 800 normal miles. If 800nm (nautical miles) then the answer is simply 800/5 = 160 hours. If normal miles then we can answer by making a conversion from knots to mph first. 5 knots = 5 * 1.15077945 = 5.75389725 mph Thus time = 800/5.75389725 = 139.036 hours (accurate to 3 decimal places).
800
One hour
800/60 = 13 and 1/3rdhours
800/7 , getting on for 115 hours
12.121212 seconds
It depends on how fast it was traveling at.
That depends on the speed of travel.
The answer depends on the rate at which you can save. For example,: -- If you could save 5 every day, then your answer would be 800 / 5 = 160 days.
If They Were Eager i Suppose 300 Years If not 800
800
Time is equal to Distance divided by speed. T = 800/69 T = 11.59420289855072463768115942029... hours
It would be 800 years.
400 to 800 years
