    Answer: 33 minutes

    Step-by-step explanation:

    Hi to answer this question we have to write a proportion

    Speed rate = 88 step per minute

    Time = 90 minutes

    So, the proportion is 88 step/min / 90 minutes

    For 33 steps per minutes = 33 / x minutes

    88/90 = 33/x

    solving for x:

    x = 33 / (88/90)

    x = 33.75 = 33 minutes.

    Feel free to ask for more if needed or if you did not understand something.
