Difficulty: Easy
Correct Answer: They are units of distance
Explanation:
Introduction / Context:
Unit analogies test whether you can correctly pair measurement units with the physical quantity they quantify. Metre (SI), kilometre (1000 metres), and mile (imperial/US customary) are all standard units used to measure length or distance in everyday and scientific contexts.
Given Data / Assumptions:
Concept / Approach:
Map each unit to the exact physical dimension. The most precise phrasing here is “units of distance”. Broad answers like “measuring anything” are incorrect because units are tied to specific quantities.
Step-by-Step Solution:
Verification / Alternative check:
Usage examples: road distances in km or miles; object lengths in metres. None of these units quantify mass, current, or thermal state.
Why Other Options Are Wrong:
They mismatch the physical property measured.
Common Pitfalls:
Accepting overly broad phrasing (“measuring anything”) which fails dimensional specificity.
Final Answer:
They are units of distance
