57 deaths per hour

Step-by-step explanation:

In one year, we have 365 days.

Now, there are 24 hours in a day.

Number of hours in one year = 365 × 24 = 8760 hours

Now, since there are half a million heart attacks deaths occurring in the United States of America each year, it means that;

There are 500000 deaths every 8760 hours.

Therefore, death rate per hour = 500000/8760 ≈ 57 deaths per hour
