Answer: 1577.14
Explanation:
From the question, we are informed that a healthy human heart beats about 1,533,000 times a year and that a sparrow's heart beats about 2,417,760,000 times in a year.
To calculate how many times faster the sparrow's heart beat compared to the human heart, we divide the sparrow's heartbeat in a year by the humans heartbeat in a year. This will be:
= 2,417,760,000 / 1,533,000
= 1577.14 times
