Let's solve the problem step by step:

1. **Juan's time**: Juan took 4.92 minutes to run one lap.
2. **Owen's time**: Owen took 1.57 minutes longer than Juan.  
   So, Owen's time = \( 4.92 + 1.57 = 6.49 \) minutes.
3. **Kevin's time**: Kevin took 1.29 minutes longer than Owen.  
   So, Kevin's time = \( 6.49 + 1.29 = 7.78 \) minutes.

### Final Answer:  
It took Kevin **7.78 minutes** to run one lap around the track.  
The correct option is **J**.
