Maria's resting heart rate is 240 beats per three minutes. What is her heart rate per minutes?
Maria's heart rate per minute is 80 beats. To find her heart rate per minute, divide 240 beats by 3 minutes. 240/3 = <<240/3=80>>80 beats. Answer: \boxed{80}.
To find out Maria's heart rate per minute, you need to divide the total heart rate by the number of minutes.
In this case, Maria's resting heart rate is given as 240 beats per three minutes. To convert this to heart rate per minute, you divide 240 by 3.
240 / 3 = 80
So, Maria's heart rate is 80 beats per minute.
To find Maria's heart rate per minute, we need to divide her heart rate (240 beats) by the time period (3 minutes).
Heart rate per minute = Total heart rate / Time period
Heart rate per minute = 240 beats / 3 minutes
Heart rate per minute = 80 beats per minute
So, Maria's heart rate is 80 beats per minute.
