Answer:
The second method gives the greater heart rate.
Step-by-step explanation:
In the second method, the age and heart rate(bpm) are in a linear relationship.
Therefore, the maximum heart rate for a 90-year-old person in the second method is = 194 - (194 - 187)7 = 145 bpm.
{Since, the maximum heart rate in the second method decreases in an A.P. having value at the age of 20 is 194 and it decreases by 7 bpm per 10 years}
Now, in the first method, the maximum heart rate for 90-year-old person is y = 220 - 90 = 130 bpm.
Therefore, the second method gives a greater heart rate. (Answer)
