North Carolina RADAR State Practice Exam

Which units can range information be expressed in?

1. Inches or centimeters

2. Kilometers or miles

3. Yards or feet

4. Meters or rods

The correct answer is: Yards or feet

Range information can be expressed in units that are commonly used to measure distance. The choice that includes yards and feet is correct because these units are part of the imperial measurement system, which is widely used in the United States, including North Carolina. Yards, often used in sports and outdoor activities, and feet, which is frequently used in construction and in everyday contexts, both provide practical measurements for range. This makes them suitable for a variety of applications such as measuring distances on a field or indicating the ranges of different objects. In contrast, the other options consist of units that may not be as readily applicable in certain contexts relevant to the practice exam. Inches or centimeters are smaller units and are generally used for precision measurements rather than broader distance ranges. Kilometers and miles, while also valid distance units, may not be as relevant in local contexts where yards and feet dominate. Meters or rods, although usable, are less common in everyday American measurements compared to yards and feet. Thus, the focus on yards and feet for range information is particularly fitting for the context of the exam and its intended applications.
