The text says "2:00 PM". Below the clock, there's a cloud with the word "Brain storming" written inside. The cloud is connected by arrows to the words "clock", "hours", "seconds", "minutes", "am", "pm", "Analogue", "Digital", "12 hours", and "24 hours". ## Recall: * 1 day = 24 hours * 1 hour = 60 minutes * 1 minute = 60 seconds * 1 day = 1440 minutes * 1 hour = 3600 seconds * 1 day = 86400 seconds **Day → hour → minute → Seconds** **1 24 60 60** **12 hour clock vs 24 hours** **0-1-2-3-4-5-6-7-8-9-10-11** ## 24 hour clock **0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16** **17 18 19 20 21 22 23 24** **Q: Convert the following:** * 11:00 pm to 24 hour clock * **Ans: 23:00 pm** * 7:30 pm to 24 hour clock * **Ans: 19:30 pm** * 7:30 am to 24 hour clock. * **Ans: 7:30 am** ## Tuesday, 8th October, 2024 **Topic: Time** **Q- Convert the following time into 24 hours.** * 8:00 pm = 20:00 pm * 3:29 am = 3:29 am * 12:55am= 00:55am * 9:05 pm = 21:05pm * 10:01pm = 22:01pm **Dear!** 24 hour time doesn't have am or pm with it.
