Which term describes the speed term meaning Nautical miles per hour?

• A. Knots
• B. Nautical miles per hour
• C. Miles per hour
• D. Kilometers per hour

Answer: (A)

Knots are the standard speed unit in navigation. One knot means you cover one nautical mile in one hour. A nautical mile is defined as 1 minute of latitude and equals about 1,852 meters, tying speed directly to global coordinates used at sea and in the air. That’s why ships and airplanes express speed in knots rather than miles per hour or kilometers per hour. For reference, 1 knot is about 1.15078 statute miles per hour or 0.51444 meters per second. While you could describe the rate as “nautical miles per hour,” the conventional, concise term used is knots.
