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 work this out in a step by step way to be sure we have the right answer.
168000
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 is 168000
