Final answer:
The mathematical problem is about representing the distance to the nearest exit door as a variable, d, which must be less than or equal to 200 feet, expressed as d ≤ 200.
Step-by-step explanation:
The problem involves representing the distance to the nearest exit door using a variable, denoted as d. If we are told that this distance is no more than 200 feet, we can write this as an inequality: d ≤ 200. This means that the value of d must be less than or equal to 200 feet. In mathematical terms, this problem is about defining a variable to represent a specific distance, and then using an inequality to describe the range within which this variable must fall. In dealing with such problems, students learn to represent real-world scenarios with mathematical expressions.
