Distance should be expressed to the nearest what?

Distance should be expressed to the nearest what?

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

Answer: (A)

Rounding distance to the nearest tenth provides the right balance between usefulness and accuracy in boating measurements. One decimal place gives enough detail for planning and communication without implying an unrealistically high level of precision in on-the-water conditions. Expressing to the nearest hundredth would suggest more precision than is typically achievable with standard instruments and charts. Giving a whole number loses important detail, and rounding to the nearest fifth isn’t the common convention used in nautical contexts. So, distance is expressed to the nearest tenth.
