    Continuing to post your homework here won't help it get done. You can ask about a certain method... but people notice when you post one question after another. I believe it's actually one of the forum rules.

    Multiply the given value (31 mi/hr) by a series of properly arranged "ones" and then cancel the resulting units.

    (31 mi/hr) * (1609m/1mi)

    Since 1609m and 1 mi are the same length it is a "one", and all you are doing here is changing units.

    Now do that for any other units you need to change.

    It works best to ask a new question in a new topic.
