    30 hours

    Step-by-step explanation:

    We need to convert these to the same period of time

    A. 300 minutes

    B. 30 hours

    30 hours * 60 minutes / 1 hour = 1800 minutes

    C. 0.3 days

    .3 days * 24 hours / 1 day * 60 minutes / 1 hours = 432 minutes

    D. 30,000 milliseconds

    30 000 ms * 1 seconds / 1000 ms * 1 minute/60 seconds =.5 minutes

    1800 minutes is the longest
