Q:

An average human heart beats 60 times per minute. If an average person lives to the age of 75, how many times does the average heart beat in a lifetime?

Accepted Solution

A:
Answer:The average number of beats in a lifetime would be 2,365,200,000Step-by-step explanation:To find the amount we need to take basic steps. The first step is multiplying the number of beats to find out how many are in an hour. Since there are 60 in a minute and 60 minutes in an hour, multiply the two. 60 beats * 60 minutes = 3,600 beats per hour. Now multiply the amount of beats in an hour by the number of hours in a day. 3,600 * 24 hours = 86,400 beats per dayNow multiply the number of days in a year. Technically there is 365 1/4 in a year, but we'll use the flat rate of 365 since that is generally the accepted answer. 86,400 * 365 days = 31,536,000 beats per yearAnd now we take that number and multiply by the number of years that he lines31,536,000 * 75 years = 2,365,200,00 beats in a lifetime
