Speed should be expressed to the nearest what?

Speed should be expressed to the nearest what?

• A. Tenth
• B. Hundredth
• C. Whole
• D. Fifth

Answer: (A)

Speed is expressed to the nearest tenth of a knot because practical navigation and most boat instruments provide readings in one-decimal precision. This level of precision gives enough detail to manage throttle, maneuvering, and compliance with speed limits without being misled by tiny fluctuations or instrument error. Rounding to the nearest tenth means numbers are read and recorded as a single decimal place; for example, a measurement of 12.34 knots becomes 12.3 knots, while 12.36 knots becomes 12.4 knots. Expressing to the nearest hundredth would imply more precision than is typically reliable or necessary, while whole-number or other larger increments would hide important small adjustments you might need for safe operation.
