60-100 bpm and that is the range of a 16 year old heart beat

Answer:

Step-by-step explanation:

Lower limit of range:

H = [tex]\frac{7}{10}[/tex](220-a)

a = 16 [given]

∴ H = [tex]\frac{7}{10}[/tex](220-16)

H = [tex]\frac{7}{10}[/tex](204)

H = [tex]\frac{7}{10}[/tex]×[tex]\frac{204}{1}[/tex]

H = [tex]\frac{1428}{10}[/tex]

H = 142.8

H = 143 beats per minute [as an integer]
