I don’t think you can..but I can be wrong
C. Decrease the intensity and inline of the treadmill.
Since Cecelia's heart rate, 187 beats per minute, is already above her target heart rate zone 138 to 175 beats per minute, she should decrease the intensity and inline of the treadmill to lower her heart rate.
Increasing intensity and incline will further hasten her heart rate. The duration of the treadmill timer does not impact Cecelia's heart rate.
