To find Ariana's current heart rate based on this measurement, we need to convert the count of 15 beats in 10 seconds to beats per minute.
There are 60 seconds in a minute, so we can use the formula:
Heart rate = (Beats / Time) * 60
Heart rate = (15 / 10) * 60 = 9 * 6 = 54 beats per minute
Therefore, Ariana's current heart rate based on this measurement is 54 beats per minute.
To calculate Ariana's current heart rate based on this measurement, you need to convert the number of beats she counted in 10 seconds to beats per minute.
First, let's assume that Ariana's heart rate remains constant throughout the day.
Since Ariana counted 15 beats in 10 seconds, we can set up the following equation to find her heart rate in beats per minute:
(15 beats / 10 seconds) * 60 seconds = 90 beats per minute.
Therefore, Ariana's current heart rate based on this measurement is 90 beats per minute.
