Final answer:
To solve the problem, we deduce that each question takes 6 minutes to read and answer and the person has 8 minutes in total. Dividing the total minutes by the minutes per question reveals the person read and answered 1 question and answered 3 more, resulting in a total of 4 questions.
Step-by-step explanation:
Let's solve the real-world problem using the given expression. The total time a person spends on the test includes both reading and answering. If it takes 5 minutes to read the question and 1 minute to answer it, each question takes 6 minutes in total. The problem states that the person takes 3 minutes to answer all of the questions, so the total time spent answering questions is 3 minutes.
Since we know that 1 question takes 1 minute to answer, we can determine the number of questions by dividing the total time spent answering (3 minutes) by the time per question (1 minute per question). Therefore, 3 minutes / 1 minute per question = 3 questions answered.
Now, we need to find how many questions were read. The total time spent on the test is 5 minutes for reading and 3 minutes for answering, which sums up to 8 minutes. The time spent per question (reading and answering) is 6 minutes, so we divide the total time by the time spent on each question. Thus, 8 minutes / 6 minutes per question = 1.33, which we round down to 1 question read. The main answer here is that the person read and answered 1 question and only answered 3 more questions for a total of 4 questions on the test.
The correct option is A) 4.
