Final answer:
Without additional context or numerical data about the flight hours, it is not possible to determine the correct compound inequality representing the range for flight hours.
Step-by-step explanation:
The student has asked which compound inequality represents the range for the flight hours, with options rounded to the nearest whole number. To answer this question correctly, we must first understand what a compound inequality is and how it is used to represent a range of values. A compound inequality consists of two inequalities joined by the word 'and' or 'or', indicating values that satisfy both inequalities or at least one of them, respectively. The correct compound inequality will represent the interval within which the flight hours fall. However, without additional context or numerical data pertaining to the flight hours, it is not possible to determine which compound inequality is correct. Additional information is required to answer the question accurately.
