The number of yards in a mile are they constant or variable? My answer is: constant Is this correct?
The correct answer and explanation is:
Correct Answer: Constant ✅
Yes, your answer is correct. The number of yards in a mile is a constant value and does not vary.
Explanation (300 Words):
A mile is a standardized unit of length used primarily in the United States and a few other countries that use the imperial system. It is defined as exactly 1,760 yards. This definition is fixed and unchanging, making the number of yards in a mile a constant.
Why It Is Constant:
The relationship between miles and yards comes from historical definitions used in the imperial system of measurement. Over time, these relationships were standardized for accuracy and consistency in fields such as land measurement, road distances, and sports.
- 1 mile = 1,760 yards
- 1 yard = 3 feet
- 1 foot = 12 inches
Because these units are defined in terms of each other, and because they have been fixed by law and international agreement, the number of yards in a mile will not change unless the system itself is redefined—which is highly unlikely.
Examples of Use:
- Road signs: In the U.S., distances are measured in miles, and race distances like a mile run (1,760 yards) use this fixed conversion.
- Navigation: Aircraft and ships might measure distance in nautical miles, but conversion from statute miles remains consistent.
Contrast With Variable Values:
A variable value changes depending on the situation or context. For instance, temperature, speed, or weight of objects may vary. However, units of measurement like miles and yards are fixed unless redefined by governing standards (like the metric system).
Conclusion:
The number of yards in a mile is constant — always 1,760 yards. Your understanding is accurate and aligns with standard measurement systems.
