    It will take Marcus 56 more minutes to deliver 100 than 72 papers

    Step-by-step explanation:

    Let's review the information given for answering this question:

    Speed that Marcus delivers papers = 9 papers in 18 minutes

    For solving the question, we should find out how long will it take to Marcus deliver 72 and 100 papers.

    1. 72 papers

    Time that it will take Marcus to deliver 72 papers = 72/9 * 18

    Time that it will take Marcus to deliver 72 papers = 8 * 18 = 144 minutes

    It will take to Marcus 144 minutes or 2 hours 24 minutes to deliver 72 papers

    2. 100 papers

    Time that it will take Marcus to deliver 100 papers = 100/9 * 18

    Time that it will take Marcus to deliver 100 papers = 11.11 * 18 = 200 minutes

    It will take to Marcus 200 minutes or 3 hours 20 minutes to deliver 100 papers

    3. Difference of time between delivering 100 and 72 papers

    200 minutes - 144 minutes = 56

    It will take Marcus 56 more minutes to deliver 100 than 72 papers
