    The inequality should be s<270. The number line should be shaded to the left.

    Step-by-step explanation:

    Miche found that most helicopters fly at speeds of less than 270 kilometers per hour.

    If s=speed of the helicopters

    Then: s<270

    Representing this on a number line:

    We have an open circle at 270. Everything to the left of the circle is shaded.

    Since the options are not given, I would list the mistakes made by Miche.

    The inequality should be s<270. The number line should be shaded to the left.
