Question

Mrs. Sawyer estimates that a quiz will take students no fewer than 11 minutes but no more than 41 minutes to complete. She allots 1 minute for passing out the papers and instructions and then students will complete a 20-question quiz. Which compound inequality represents x, the average amount of time a student spends on each question?


1 + 20x > 11 or 1 + 20x < 41

11 < 1 + 20x < 41

11 ≤ 1 + 20x ≤ 41

1 + 20x ≥ 11 or 1 + 20x ≤ 41

Answer 12

The shortest amount of time that a student spends on the entire quiz ranges from 11 minutes to 41 minutes. There are 20 questions. Thus, the average amount of time spent on each question ranges from (approx.) (11 minutes)/20 questions to (41 minutes)/20 questions. Call this average "x."

Which of the four given answers seems to answer the question best?

B. 11 < 1 + 20x < 41
