Answer 1

To determine Kani's heart rate one minute after running, we can use the information provided.

1. Kani's heart rate immediately after running is 193 beats per minute.
2. One minute later, his recovery heart rate is 25 beats per minute.

The recovery heart rate is typically calculated by subtracting the heart rate after one minute from the heart rate right after exercise. If we denote Kani's heart rate one minute after running as \( HR_{1\text{min}} \), we can set up the following relationship:

\[
HR_{1\text{min}} - 193 = -25
\]

This equation suggests that the recovery heart rate decreased to 25 beats, which means:

\[
HR_{1\text{min}} = 193 - 25
\]

Thus, we get:

\[
HR_{1\text{min}} = 168 \text{ beats per minute}
\]

Therefore, Kani's heart rate one minute after running was **168 beats per minute**.
