A person’s maximum heart rate is the highest rate, in beats per minute, that the person’s heart should reach. A person’s age added to his or her maximum heart rate is 220. Write and solve an equation to find the maximum heart rate of a 16-year old.
16 + x = 220
x = 220 - 16
x = 204
To find the maximum heart rate of a 16-year old, we can use the equation given, which states that a person's maximum heart rate is their age added to 220.
Let's denote the maximum heart rate of a 16-year old as MHR (Maximum Heart Rate). The equation can be expressed as:
MHR + 16 = 220
To solve for MHR, we need to isolate it on one side of the equation. Let's do that:
MHR = 220 - 16
MHR = 204
Therefore, the maximum heart rate of a 16-year old is 204 beats per minute.
