Introduction
What is Time?
Time is a measurement that helps us track when 
events happen, how long they last, and the order 
in which they occur. Time helps us organize our 
daily activities from waking up to going to bed.
What is a Timetable?
Timetables are special charts or schedules that 
show when different activities happen. They help 
us manage our time efficiently by planning when 
to study, play, eat, and rest.

AM (Ante Meridiem) covers midnight to noon (12:00 AM to 11:59 AM), while 
PM (Post Meridiem) covers noon to midnight (12:00 PM to 11:59 PM).
The 24-Hour Day

Q u e s t i o n
If it is 3:45 PM now, what will be the time after 2 
hours 30 minutes?
Solution
Start with the given time
We begin with 3:45 PM as our starting point.
Add the hours
3:45 PM + 2 hours = 5:45 PM
Add the minutes
5:45 PM + 30 minutes = 6:15 PM
Final answer
Therefore, after 2 hours and 30 minutes, the 
time will be 6:15 PM.
