# --description--
|
||
|
||
Given the angles for the hour and minute hands of an analog clock in degrees (clockwise from 12), return the time in spoken English.
|
||
|
||
Convert the minute hand angle to minutes (360° = 60 minutes), then use the following rules:
|
||
|
||
| Minutes | Spoken |
|
||
|---------|--------|
|
||
| 0 | `"Y o'clock"` |
|
||
| 15 | `"quarter past Y"` |
|
||
| 1–29 (excluding 15) | `"X minutes past Y"` |
|
||
| 30 | `"half past Y"` |
|
||
| 45 | `"quarter to Z"` |
|
||
| 31–59 (excluding 45) | `"X minutes to Z"` (where `X` is 60 - minutes) |
|
||
|
||
Where `Y` is the current hour and `Z` is the next hour, both derived from the hour hand angle (360° = 12 hours).
|
||
|
||
Note: Hand angles may not land exactly on a number, consider rounding them somehow.

`get_spoken_time(90, 0)` should return `"3 o'clock"`.
|

```js
|

({test: () => { runPython(`
|
||
from unittest import TestCase
|
||
TestCase().assertEqual(get_spoken_time(90, 0), "3 o'clock")`)
|
||
}})
|
||
```
|
||
|
||
`get_spoken_time(160, 120)` should return `"20 minutes past 5"`.
|
||
|
||
```js
|
||
({test: () => { runPython(`
|
||
from unittest import TestCase
|
||
TestCase().assertEqual(get_spoken_time(160, 120), "20 minutes past 5")`)
|
||
}})
|
||
```
|
||
|
||
`get_spoken_time(255, 180)` should return `"half past 8"`.
|
||
|
||
```js
|
||
({test: () => { runPython(`
|
||
from unittest import TestCase
|
||
TestCase().assertEqual(get_spoken_time(255, 180), "half past 8")`)
|

}})
|

```
|

`get_spoken_time(67.5, 92)` should return `"quarter past 2"`.

}})
|

```
|
||
|
||
`get_spoken_time(200, 240)` should return `"20 minutes to 7"`.
|
||
|

```js
|

({test: () => { runPython(`
|
||
from unittest import TestCase
|
||
TestCase().assertEqual(get_spoken_time(200, 240), "20 minutes to 7")`)

```
|

`get_spoken_time(322.5, 273)` should return `"quarter to 11"`.

`get_spoken_time(117.5, 335)` should return `"5 minutes to 4"`.
