Calculate your average resting pulse rate. Show your calculation.

Question 1:

Step 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

Step 2: Divide the total by the number of readings to find the average.
Average heart rate = $\frac{total heart rate readings}{number of readings}$
Average heart rate = $\frac{450~bpm}{3}$
Average heart rate = $150$ bpm

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

Question 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.

Question 3 (from instructions):
Two places on the body where pulse rate can be measured are the radial artery (wrist) and the carotid artery (neck).
