What is the standard speed unit in navigational problems?

• A. Knots
• B. Miles per hour
• C. Kilometers per hour
• D. Feet per second

Answer: (A)

In navigation, speed is measured in knots because distances on charts are in nautical miles and time is in hours. One knot means one nautical mile per hour, which keeps calculations simple and directly tied to how positions and courses are plotted on navigational charts. For example, traveling 30 nautical miles in 2 hours equals 15 knots. Using miles per hour or kilometers per hour would require converting nautical miles to statute miles or kilometers, adding extra steps and potential errors. Feet per second isn’t practical for long-distance navigation either. So the standard speed unit in navigational problems is knots.
