    1) Katie arrived at 4:00.
    2) Mason was early by 20 minutes.
    3) Reece thought that his appointment was at 12:55.
    4) Laura arrived at 4:10.

    I disagree with Ron. This is because the times that say am, eg, 10:17 am and 5:09 am should be the same time in the 24 hour times, Ron is correct with the pm times, eg, 1:45 pm and 8:39 pm.

    I disagree with Ron because if you’re converting between 12 and 24-hour times if it is in AM all you need to do is take the am off. It’s also the same between 12 and 1 o’clock but its PM.
