Age Group Normal Heart Rate at Rest Children (ages 6-15)70-100 beats per minute. Adults (age 18 and over) 60-100 beats per minute.
you divide the number of 15 seconds by 15 and then times it by 60
Count how many times your heart beats....for one minute. Or count for 15 seconds and multiply by 4.
120
90 beats per minute.
Locate your jugular, put your index and middle finger on it and count how many beats in 15 seconds, then multiply this figure by 4.
15, 000, 000.
sit down. relax. count the number of times your pulse beats in 15 seconds and multiply that by 4.
18(beats)x4(intervals of 15 in 60)=72bpm
Sit quietly and find your pulse in your wrist. Use your first two fingers, not your thumb. Count the number of beats for 15 seconds, and multiply the number of beats times 4 to get the heart rate per minute. For example, if you count 18 beats in 15 seconds, your heart rate would be 18 x 4, which would be 72 beats per minute.
There will be 403200 beats in the month of February as 150 is multiplied by 4 for beats in 24 hours then by 28 days.
