--description--

Given the speed you are traveling in miles per hour (MPH), and a speed limit in kilometers per hour (KPH), determine whether you are speeding and if you will get a warning or a ticket.

  • 1 mile equals 1.60934 kilometers.
  • If you are traveling less than or equal to the speed limit, return "Not Speeding".
  • If you are traveling 5 KPH or less over the speed limit, return "Warning".
  • If you are traveling more than 5 KPH over the speed limit, return "Ticket".

--hints--

speed_check(30, 70) should return "Not Speeding".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(speed_check(30, 70), "Not Speeding")`)
}})

speed_check(40, 60) should return "Warning".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(speed_check(40, 60), "Warning")`)
}})

speed_check(40, 65) should return "Not Speeding".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(speed_check(40, 65), "Not Speeding")`)
}})

speed_check(60, 90) should return "Ticket".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(speed_check(60, 90), "Ticket")`)
}})

speed_check(65, 100) should return "Warning".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(speed_check(65, 100), "Warning")`)
}})

speed_check(88, 40) should return "Ticket".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(speed_check(88, 40), "Ticket")`)
}})

py
def speed_check(speed_mph, speed_limit_kph):

    return speed_mph

--solutions--

py
def speed_check(speed_mph, speed_limit_kph):
    speed_kph = speed_mph * 1.60934

    if speed_kph <= speed_limit_kph:
        return "Not Speeding"

    over = speed_kph - speed_limit_kph

    if over <= 5:
        return "Warning"

    return "Ticket"
