Answer 2

You should first calculate the number of minutes in a day. There are 60 minutes and hour, and 24 hours a day; multiplying these together will give you the total amount of minutes in a day:

60 * 24 = 1440

If you divide this by 3, you will get the amount of times a day the whale's heart beats 24 times:

1440 / 3 = 480. A grey whale's heart beats 24 times a day 480 times; multiply these together and have your final answer:

480 * 24 = 11520

Answer:
A grey whale's heart beats 11,520 times in a day.
