Explanation:
Number of beats in 15 seconds = _12__. Now multiply this number by 4 to tell how many times your heart beats in one minute. Number of beats in 15 seconds __18_ X 4 = _72__ beats per minute. Now multiply this times 60 to tell how many times your heart beats in one hour. Number of beats in 1 minute = _72__ X 60 = _4,320__ beats per hour. Now multiply this times 24 to tell how many times your heart beats in one day. Number of beats in 1 hour = _4,320__ X 24 = __103,680_ beats per day.
Number of beats in 15 seconds = 12. Now multiply this number by 4 to tell how many times your heart beats in one minute. Number of beats in 15 seconds 18 Â X 4 = 72 beats per minute. Now multiply this times 60 to tell how many times your heart beats in one hour. Number of beats in 1 minute = 72 X 60 = 4,320 beats per hour. Now multiply this times 24 to tell how many times your heart beats in one day. Number of beats in 1 hour = 4,320 X 24 = 103,680 beats per day.
