    1) It on works on the first 12 hours of the day. It doesnt not work for am hours. If you wanted to change 5:09 am to 24 hour time it would be 05:09 not 17:09

    I agree with Ron because there is 12 hours in a whole clock turn and if your converting 12 hour times to 24 hour times then you can just add 12 to get to the right answer.

    I do not agree with Ron.I know this because if it a a.m you have to minus the 12 but if it a p.m you have to add the 12 and Ron didn’t care about the a.m and p.m,he just added the 12 for all of them when some of the time was a.m,that was Ron mistake.

    I disagree with Ron because in Am you can’t add 12 because they are in the same hours. The only time you can start adding 12 is in pm which is starting from 1pm.

    4. Laura was 30 minutes late so she arrived at 4:10.
    5. Shelby is 25 minutes early so she should arrived at 6:35.

    Ron’s mistake is that he got some things correct and some incorrect he got some stuff wrong because for the pm or am and for the am you are supposed to have been the same so in 24 hours it just has a 0 if under 10.
