Step-by-step solution

2 steps

Part 1· 2 steps

  1. Add the three heart rate readings.

    Total heart rate readings = first reading + second reading + third reading
    Total = 145 bpm + 155 bpm + 150 bpm
    Total = 450 bpm

  2. Divide the total by the number of readings to find the average.

    Average heart rate = total heart rate readingsnumber of readings\frac{\text{total heart rate readings}}{\text{number of readings}}
    Average heart rate = 450 bpm3\frac{450~\text{bpm}}{3}
    Average heart rate = 150 bpm

    Average heart rate = 150 bpm\boxed{150~\text{bpm}}

Part 2

You must take your pulse twice on each wrist to obtain more accurate and reliable measurements. A single reading may vary due to slight differences in counting or momentary fluctuations in heart rate, so averaging two readings reduces error and ensures consistency.

Part 3

(from instructions)

Two places on the body where pulse rate can be measured are the radial artery (wrist) and the carotid artery (neck).
