A polar explorer set off from one point to another on a sled pulled by a team of five dogs. After 24 hours, two dogs perished, causing the explorer's speed to reduce to \( \frac{3}{5} \) of the original speed, resulting in a two-day delay.

- "Alas!" exclaimed the explorer. "If the two fallen dogs had run an additional 120 km, I would have been delayed by only one day."
