question mark

A tortoise and a hare are in a road race to defend the honor of their breed. The tortoise crawls the entire 1000 meters at a speed of 0.2 m/s. The rabbit runs the first 200 meters at 2 m/s, stops to take a nap for 1.3 hours, and awakens to finish the last 800 meters with an average speed of 3 m/s. Who wins the race and by how much time?

To determine the winner of the race between the tortoise and the hare, we need to calculate the total time each competitor takes to complete the 1000 meters. Let's break down their journeys step by step.

The Tortoise's Journey

The tortoise moves at a steady speed of 0.2 meters per second for the entire distance of 1000 meters. To find out how long it takes, we can use the formula:

  • Time = Distance / Speed

Plugging in the values:

  • Distance = 1000 meters
  • Speed = 0.2 m/s

Calculating the time:

  • Time = 1000 m / 0.2 m/s = 5000 seconds

The Hare's Journey

The hare's journey is a bit more complex due to the nap. Let's break it down into two segments:

First Segment: The Initial 200 Meters

The hare runs the first 200 meters at a speed of 2 m/s. Using the same formula:

  • Distance = 200 meters
  • Speed = 2 m/s

Calculating the time for this segment:

  • Time = 200 m / 2 m/s = 100 seconds

Nap Time

After running, the hare takes a nap for 1.3 hours. We need to convert this time into seconds:

  • 1.3 hours = 1.3 × 3600 seconds = 4680 seconds

Second Segment: The Last 800 Meters

Finally, the hare runs the remaining 800 meters at an average speed of 3 m/s:

  • Distance = 800 meters
  • Speed = 3 m/s

Calculating the time for this segment:

  • Time = 800 m / 3 m/s ≈ 266.67 seconds

Total Time for the Hare

Now, we can sum up all the time segments for the hare:

  • Time for first segment: 100 seconds
  • Nap time: 4680 seconds
  • Time for second segment: 266.67 seconds

Total time for the hare:

  • Total Time = 100 + 4680 + 266.67 ≈ 5046.67 seconds

Comparing the Times

Now that we have the total times for both competitors:

  • Tortoise: 5000 seconds
  • Hare: 5046.67 seconds

To find out who wins and by how much time, we subtract the tortoise's time from the hare's time:

  • Time difference = 5046.67 seconds - 5000 seconds ≈ 46.67 seconds

Final Outcome

The tortoise wins the race by approximately 46.67 seconds. This classic tale emphasizes the value of perseverance and steady effort over speed and overconfidence. In this case, the tortoise's consistent pace allowed it to finish the race ahead of the hare, despite the hare's initial speed advantage.
