Give the step-by-step reasoning process and then the final answer. Aren's flight from New York to Hawaii will take 11 hours 20 minutes. He spends 2 hours reading, 4 hours watching two movies, 30 minutes eating his dinner, 40 minutes listening to the radio, and 1 hour 10 minutes playing games. How many hours does he have left to take a nap?
The flight from NY to Hawaii will take 60 x 11 + 20 = 680 minutes. All the activities will take 120 + 240 + 30 + 40 + 70 = 500 minutes. For his nap, he has 680 - 500 = 180 minutes. To convert minutes to hours, he has 180 / 60 = 3 hours.
The final answer: 3.
