Porter is on the swim team. In addition to swimming, he runs as part of his training. Porter checks his heart rate halfway through his training session.His heart beats 53 times in a 1/3 minute, how many times does his heart beat in a minute?

Answer 1

To find Porter's heart rate in beats per minute (bpm), we need to determine how many times his heart beats in one full minute based on the number of beats recorded in 1/3 of a minute.

Porter's heart beats 53 times in 1/3 of a minute.

To calculate the heart rate in beats per minute, we can use the following formula:

\[ \text{Heart Rate (bpm)} = \text{Beats in } \frac{1}{3} \text{ minute} \times \text{Number of } \frac{1}{3} \text{ minutes in 1 minute} \]

Since there are 3 segments of 1/3 in a full minute (because 1 divided by 1/3 = 3), we can multiply the number of beats in 1/3 minute by 3:

\[ \text{Heart Rate (bpm)} = 53 \times 3 = 159 \text{ bpm} \]

Therefore, Porter's heart beats 159 times in a minute.
