Answer: Neither Sandra nor Marissa will be in her THR zone.

Explanation:

1) Actual pulse of both Sandra and Marissa : 144 bpm

2) Decrease of 20 bpm ⇒ 144 bpm - 20 bpm = 124 bpm

3) Sandra's TRH is in the range 135 - 172 bpm.

Since 124 < 135, she will be below the range.

4) Marissa's TRH range is 143 - 176 bpm.

Since, 124 < 143, she is below the range

In conlusion, neither Sandra nor Marissa will be in her THR zone.

Sandra's pulse is 144 bpm. If she decreases it by 20 bpm,
it will be 124 bpm. Her TRH is the range of 135 - 172 bpm,
so she will be below it.

Marissa's pulse is 144 bpm. If she decreases it by 20 bpm,
it will be 124 bpm. Her TRH is the range of 143 - 176 bpm,
so she will be below it.

Neither girl will be in her THR.
