--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].

({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].

({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].

({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].

({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].

({test: () => { runPython(`
from unittest import TestCase
