Question

A person who is 15 years old has a target heart rate range of? A. 132-176 B) 123-164 C) 114- 152 D) 99-132

Answer 1

The maximum heart rate is calculated by removing the given age from 220. In this case, we are given 15 as the value for age. So, we have: 220 15 = 205.
To calculate the heart rate range, we have to calculate for three zones:
Zone 1= Maximum heart range * 0.6 = 205 * 0.6 = 123.
Zone 2 = Maximum heart range * 0.7 = 205 * 0.7 = 143.5.
Zone 3 = Maximum heart range * 0.8 = 205 * 0.8 = 164.
Therefore, the heart rate range = 123 - 164.
Thus, the correct option is B.

Answer 2

Well dude it depends of many facts, for example, if you are doing sport it's obvious that you traget heart will growth but talking into account a normal person with 15 years, it will be probably a low target but it depends of the effort he doing or more aspects. I hope I help (if I have bad my spelling grammar is because I am a 15 year old spanish guy xd)
