James listens to super-fast music. It is 200 beats per minute. He listens to 2 hours of music a day. How many beats does he hear per week? Let's answer step by step:
He listens to 2 * 60 = 120 minutes of music a day. So he hears 200 * 120 = 24000 beats per day. That means he hears 24,000 * 7 = 168,000 beats per week. The answer: 168000.
