[old] Achilles and the Tortoise [old] Achilles and the Tortoise

English ES JA RU

In a race, the quickest runner can never overtake the slowest, since the pursuer must first reach the point whence the pursued started, so that the slower must always hold a lead.

– as recounted by Aristotle, Physics VI:9, 239b15

"Achilles and the tortoise" is one of the famous Zeno's paradoxes. Nikola wants to check the validity of this paradox and for this purpose he constructed two robots: Achilleborg (A1 -- fast agile prototype) and Tortoimenator (T2 -- heavy slow cyborg).

A1 is faster than T2, so it has...

You are given A1 and T2’s speed in m/s as well as the length of the advantage T2 has in seconds. Try to count the time when A1 will catch up with T2 (count from the T2’s start). The result should be given in seconds with precious ±10-8.

Input: Three arguments. The speed of A1 and T2, and the advantage as integers.

Output: The time when A1 will catch up with T2 (count from the T2’s start) as an integer or float.

Example:

chase(6, 3, 2) == 4
chase(10, 1, 10) == 11.11111111

How it is used: Let's go back to school for a moment and remember the basic math principles. Sometimes simple arithmetic allows us to easily resolve philosophical paradoxes.

Precondition:
t2_speed < a1_speed < 343
0 < advantage ≤ 60

CheckiO Extensions

CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.

In order to install CheckiO client you'll need installed Python (version at least 3.8)

Install CheckiO Client first:

pip3 install checkio_client

Configure your tool

checkio --domain=js config --key=

Sync solutions into your local folder

checkio sync

(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)

checkio serv -d

Alternatevly, you can install Chrome extension or FF addon

checkio install-plugin
checkio install-plugin --ff
checkio install-plugin --chromium

Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
