Highly energetic particles originating from cosmic rays approach the surface of Earth with a speed close to the speed of light. The k-meson (or Kaon) reaches the Earth's atmosphere with a speed of 0.88c. The mean lifetime of a K-meson at rest is 1.23 × 10−8 s. Calculate the average distance, as measured from Earth's frame, the K-meson particles travel before decaying.
