Err... 10 knots is a measurement of speed, not power, so your question has no answer.
To convert knots to horsepower in boating, you can use the formula: Horsepower = (Speed in knots × Weight in pounds) / 375. For a rough estimate, if a boat weighs around 5,000 pounds, then 10 knots would require approximately 13.3 horsepower. However, the exact horsepower needed can vary significantly based on the boat's design, hull shape, and other factors.
10 knots = 11.51 mph
There are 20,000 knots in 10 nautical miles.
Knots is a measurement of speed. Horsepower is a measurement of power. To obtain that speed on water is probably not possible. To obtain that speed in air takes allot of horsepower. That is over Mach 2 (twice the speed of sound),
10 kilowatts is 13.6 metric horsepower.

10 knots is 11.50 miles, so 50 miles is faster
