What was the question for this implicit rationale, and corresponding answer?
The first movie was 60 + 30 = 90 minutes long since an hour has 60 minutes. The second movie was 90 + 30 = 120 minutes long. It took them a total of 90 + 120 = 210 minutes to watch the two movies. It took them 10 x 2 = 20 minutes to cook the fries. Thus, it took them a total of 10 + 20 = 30 minutes to cook. So, they spent 210 + 30 = 240 minutes watching the movies and cooking. In hours, this is equal to 240 / 60 = 4 hours.
 The answer: 4
