10.2888888 is the speed in meters per second of a ship traveling at 20 knots.
6.32766667 meters per second ==
1/20 hour = 3 minutes
Easy! Divide by 200. So 1000 feet per minute = 5 metres per second (roughly). It also equals 10 knots incidentally.
To determine how long a ship traveling at 16 knots would take to cover 100 miles, you can use the formula: time = distance ÷ speed. First, convert knots to miles per hour; 1 knot equals approximately 1.15 miles per hour, so 16 knots is about 18.4 miles per hour. Dividing 100 miles by 18.4 miles per hour gives approximately 5.43 hours, or about 5 hours and 26 minutes.
To convert knots to miles per hour, you can multiply the speed in knots by 1.15078. Therefore, 70 knots is approximately 80.6 miles per hour.

The speed in meter/scond is 15x1800 m/3600 s = 7.5 meters/second where a Knot is a Nautical mile of 1800 meters/hour.
20 knots is equivalent to approximately 10.29 meters per second.
To convert knots to meters per second, multiply the speed in knots by 0.514444. This conversion factor accounts for the difference in the units of measurement used for speed (nautical miles per hour for knots and meters per second).
1/20 hour = 3 minutes
.089 knots per meter or 11.23 meters per knots
1 Knot = 0.514444444444444 Meters per Second different calculations also use 0.5148
30 Knots = 55.56 Kilometers per Hour
21 knots = 24.2 mph
Knots is the form of measurement of the speed of boats. It was originally measured by a board being dropped in the water with a rope tied to it, the other end of the rope was tied to the stern of the boat. This rope had knots tied into it at 14.4 meters apart. The one sailor would use a 30 second glass sand timer while another would let the rope out behind the boat. When 30 seconds were up the number of knots on the rope that had gone thru the sailors hands were the speed they were traveling. Dividing that 14.4 meters by 30 seconds told them that one knot equaled 1.85166 kilometers per hour, or one nautical mile.
250 knots = 287.7 mph
To convert knots to inches per second, use the conversion factor of 1 knot = 1.68781 inches per second. Multiply the speed in knots by this conversion factor to get the equivalent speed in inches per second.
