Pretty simple math.
1 knot is 1.3 miles per hour.
650 x 1.3 mph = 845 miles per hour.
50,000,000 miles / 845 mph = 59,171.6 hours
59,171.6 hours / 24 (hours in a day) = 2,465.5 days
2,465.5 days / 365 (days in a year) = 6.75 years
If you were to travel 4 miles at 6 knots, It would be approximately 34 minutes and 50 seconds!
One hour.
It depends upon your velocity (expressed in knots).
1500/11 hours
36/14 hours
139.04 hours or 5.7932 days.
Ten seconds.
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).
* Use the formula: distance = speed x time. In this case, if you divide the distance by the speed, you get time.* "Knots" means "nautical miles per hour".

This will vary based on the cruise ship and how fast it is going. Most cruise ships travel at the speed of 21 to 24 knots per hour. 1 knot = 1.15 mph. 21 knots is equal to 24.15 mph so it would take you approximately 53 hours to travel 1280 miles.
It would take 10 seconds.
