On the average your heart beats about 72 times per min. At this rate, about how many times will it be 30 days in a year in your lifetime if you live to be 72?

    Please reread your question. It doesn't make any sense (be 30 days in a year??).

    Clarify and repost and we'll help you find the answer to this problem.

    I think the child has left out commas. If it beats 72/minute, then in 30 days it will be 72 x 60 (for one hour) x 24 ( for one day) x 30 (days) then that answer by 12 (months) then that answer x 72.
