Ronis correct because if you add 12 on to a number when caculating time here is an example 5 +12 = 17

You have to add 12 to a 12 hour clock to make it a 24 hour clock!

How I figured this out is from school always add 12 to your HOUR number

Gold:
1) Katie arrived at 2:05. :/
2) Mason was 20 minutes early.
3) Reece thought her the appointment was at 12:55 not 12:30!
4) Laura arrived at 4:10 not at the proper time 3:40!
5) Shelby arrived at 6:35!
One thing to point out on the sheet for gold 6:10 and 5:25 has a fullstop in the middle of the hour and minutes where’s the colon?π
Platinum:
Yes I for one agree with Ron because whenever you want to turn a 12 hour clock to 24 hour clock then just add 12 because 12+12=24.πππ»π€

Ron is wrong because both times need to be the same am and pm
10:17 am – 10:17 in 24 hour clock
5:09 am – 5:09 in 24 hour clock
