Answer:
12:30PM
Step-by-step explanation:
Known information:
There are 4 classes.
Each class is 1 hour.
There are 10 minutes between classes, like a break.
Draw a diagram:
start-CLASS1, break, CLASS2, break, CLASS3, break, CLASS4-end
There are 3 breaks because there are no breaks before and after the first and last classes.
Multiply the number of classes by the time length for class.
Multiply the number of breaks by the time length for breaks.
Add the two numbers together to get the total school time:
Classes: 4*1h = 4h
Breaks: 3*10min = 30min
4h + 30min = 4h 30min
Calculate 4h and 30min after 8:00 AM.
Add 4 hours and 30 minutes to 8.
. 8:00
<u>+ 4:30</u>
. 12:30
In the AM/PM clock (not 24 hour clock) there are 12 hours. After 12:59, it becomes 1:00, not 13:00.
Since "12:30" is possible on the AM/PM, we do not need to fix it.
The AM/PM clock changes at 12:00.
This means that after 11:59PM it becomes 12:00AM.
After 11:59AM it becomes 12:00PM. (Usually lunch)
Since 12:30 passed 11:59, the AM/PM sign changes.
The fourth class ends at 12:30PM.
