Answer:
10:30 am
Step-by-step explanation:
First we must convert the 10:25 pm to the 24 hour clock so we wont have negative results. To do this we add 12 hours to the given time (because it is between 1 pm and 11:59 pm)
10:25 hours+12 hours=22:25 hours
to this 22:25 hours we will substract 11:55 minutes to know what time was before that time passed like this:
-First we substract the minutes:
25-55=-30
we obtain a negative result, when this happens we add 60 to the first value (25)
85-55=30 (Minutes)
and substract 1 from the first value of the hours so we wont have 22 but 21. And we substract normally now having the minutes ready
21-11=10( Hours)
The time was 10:30 am
