# --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")`)
|
|
}})
