English:
    1. Having internet connection with speed 100 Mb/s
    2. How long will take to download 100 MB?
    3. To calculate time divide file size by speed
    4. Note, that all values must be `int` (type cast if needed)
    5. In Calculations use floordiv (`//`)
    6. Run doctests - all must succeed

Polish:
    1. Mając łącze internetowe 100 Mb/s
    2. Ile zajmie ściągnięcie pliku 100 MB?
    3. Aby wyliczyć czas podziel wielkość pliku przez prękość
    4. Zwróć uwagę, że wszystkie wartości mają być `int`
       (rzutuj typ jeżeli potrzeba)
    5. W obliczeniach użyj floordiv (`//`)
    6. Uruchom doctesty - wszystkie muszą się powieść

Hints:
    * 1 Kb = 1024 b
    * 1 Mb = 1024 Kb
    * 1 B = 8 b
    * 1 KB = 1024 B
    * 1 MB = 1024 KB
    * Use // to get floor division as int

Tests:
    >>> import sys; sys.tracebacklimit = 0

    >>> assert bandwidth is not Ellipsis, \
    'Assign your result to variable `bandwidth`'
    >>> assert size is not Ellipsis, \
    'Assign your result to variable `size`'
    >>> assert duration is not Ellipsis, \
    'Assign your result to variable `duration`'
    >>> assert type(bandwidth) is int, \
    'Variable `bandwidth` has invalid type, should be int'
    >>> assert type(size) is int, \
    'Variable `size` has invalid type, should be int'
    >>> assert type(duration) is int, \
    'Variable `duration` has invalid type, should be int'

    >>> duration
