--description--

Given a number of miles ran, and a time in "MM:SS" (minutes:seconds) it took to run those miles, return a string for the average time it took to run each mile in the format "MM:SS".

  • Add leading zeros when needed.

--hints--

mile_pace(3, "24:00") should return "08:00".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(mile_pace(3, "24:00"), "08:00")`)
}})

mile_pace(1, "06:45") should return "06:45".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(mile_pace(1, "06:45"), "06:45")`)
}})

mile_pace(2, "07:00") should return "03:30".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(mile_pace(2, "07:00"), "03:30")`)
}})

mile_pace(26.2, "120:35") should return "04:36".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(mile_pace(26.2, "120:35"), "04:36")`)
}})

py

    minutes, seconds = map(int, duration.split(":"))
    total_seconds = minutes * 60 + seconds
    avg_seconds_per_mile = total_seconds / miles

    avg_minutes = int(avg_seconds_per_mile // 60)
    avg_seconds = round(avg_seconds_per_mile % 60)

    return f"{avg_minutes:02d}:{avg_seconds:02d}"
