Question

At Oxley college recess finishes at 10:50am and is followed by two 50 minute periods before lunch. At what time does the lunch hour end?

Answer 1

Answer:

Lunch hour ENDS at 1:30 PM

Step-by-step explanation:

Oxley college recess finishes at 10:50 am.

There are two periods after recess  before lunch break.

Each period is of 50 mins.

Thus we need to add 50+50= 100 mins after the recess to get the start time of the lunch hour.

Thus, start time of the lunch hour = 10:50 AM + 100 mins

Thus, start time of the lunch hour = 10:50 AM + 1 Hour + 40 mins

Thus, start time of the lunch hour = 11:50 AM + 10 mins + 30 mins

Thus, start time of the lunch hour = 12:00 PM + 30 mins

Thus, start time of the lunch hour = 12:30 PM.

Now, The time for luch is one hour, as it is said to be 'Lunch Hour'

Thus adding one hour in the start time we get;

End of the lunch hour = Start of the lunch hour + Lunch time

End of the lunch hour = 12:30 PM + 1 hour

End of the lunch hour = 1:30 PM
