# --description--
|
|
|
|
Given an array of numbers representing the speed at which vehicles were observed traveling, and a number representing the speed limit, return an array with two items, the number of vehicles that were speeding, followed by the average amount beyond the speed limit of those vehicles.
|
|
|
|
- If there were no vehicles speeding, return `[0, 0]`.
|
|
|
|
# --hints--
|
|
|
|
`speeding([50, 60, 55], 60)` should return `[0, 0]`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(speeding([50, 60, 55], 60), [0, 0])`)
|
|
}})
|
|
```
|
|
|
|
`speeding([58, 50, 60, 55], 55)` should return `[2, 4]`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(speeding([58, 50, 60, 55], 55), [2, 4])`)
|
|
}})
|
|
```
|
|
|
|
`speeding([61, 81, 74, 88, 65, 71, 68], 70)` should return `[4, 8.5]`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(speeding([61, 81, 74, 88, 65, 71, 68], 70), [4, 8.5])`)
|
|
}})
|
|
```
|
|
|
|
`speeding([100, 105, 95, 102], 100)` should return `[2, 3.5]`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(speeding([100, 105, 95, 102], 100), [2, 3.5])`)
|
|
}})
|
|
```
|
|
|
|
`speeding([40, 45, 44, 50, 112, 39], 55)` should return `[1, 57]`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(speeding([40, 45, 44, 50, 112, 39], 55), [1, 57])`)

}})
