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 42 beats in 1/4 minute, how many times does his heart beat in a minute.

Answer 1

To find out how many times Porter's heart beats in one minute, we first need to determine how many 1/4 minute intervals are in a full minute. Since there are 4 intervals of 1/4 minute in one minute, we can use this information to calculate the total heart beats per minute.

Porter's heart beats 42 times in 1/4 minute. Therefore, in one minute, his heart beats:

\[ 42 \text{ beats} \times 4 = 168 \text{ beats} \]

So, Porter's heart beats 168 times in a minute.
