If you are 12 years old, which math problem would give you your maximum heart rate? Response areaAfter finding your maximum heart rate, remember your target heart rate zone is 70-85% of you maximum heart rate, what would be your lower range or your target heart zone? Response area What would be your upper limit?Response area100, 208, 220 - 12, 200 + 12, 146 ,220+12
170 , 200-12, 150, 167
To find your maximum heart rate as a 12-year-old, you would subtract your age from 220. So, 220 - 12 = 208 beats per minute.
Your target heart rate zone would be 70-85% of your maximum heart rate. So, the lower range would be 70% of 208, which is 0.7 x 208 = 146.4 beats per minute. Rounding down, your lower range would be 146 bpm.
The upper limit of your target heart rate zone would be 85% of 208, which is 0.85 x 208 = 176.8 beats per minute. Rounding up, your upper limit would be 177 bpm.
So, your target heart rate zone would be between 146 bpm and 177 bpm.
