Oh, dude, math time! So, if the heart beats 72 times in a minute, that means it beats 18 times in a quarter of a minute. Just divide 72 by 4 and boom, you got your answer. Like, it's simple math, but hey, your heart's doing all the hard work anyways, right?
Each 15-minute period is called a quarter of an hour because an hour is divided into four equal parts, and each part represents one-quarter of the total time. Since there are 60 minutes in an hour, dividing that by four gives you 15 minutes. Thus, each 15-minute segment is one-quarter, or "quarter," of the hour.
40-45 beats per minute
If that's "a quarter to," it means fifteen minutes before the hour; the minute hand on the 9.
