Doctors use the term maximum heart rate (MHR) when referring to the quantity found by starting with 220 beats per minute and subtracting 1 beat per minute for each year
of a person's age. Doctors recommend exercising 3 or 4 times each week for at least
20 minutes with your heart rate increased from its resting heart rate (RHR) to its
training heart rate (THR), where
THR = RHR +.65(MHR - RHR)
Which of the following is closest to the THR of a 43-year-old person whose RHR is
54 beats per minute?
