Answer:
162 beats per minute
Step by step solved:
To find the target ceiling, we need to multiply the maximum heart rate (MHR) by 0.90. The formula can be expressed as:
Target Ceiling = MHR x 0.90
Let's say that the person's MHR is 180 beats per minute. We can substitute this value into the formula and solve:
Target Ceiling = 180 x 0.90
Target Ceiling = 162
Therefore, the target ceiling for this person is 162 beats per minute.
