The Time: 4:40 a.m.
To find the time that is 3 hours before 4:40 a.m., we need to subtract 3 hours from the given time.
Subtracting 3 hours:
- We know that there are 60 minutes in an hour.
- So, we can subtract 3 hours from the given time by subtracting 3 times 60 minutes.
Calculating the minutes:
- 3 hours is the same as 3 times 60 minutes, which is equal to 180 minutes.
- Subtracting 180 minutes from 40 minutes gives us a negative result, -140 minutes.
Converting the minutes:
- Since we have a negative result for the minutes, we need to borrow 1 hour from the hours section.
- Subtracting 140 minutes from 60 minutes gives us 60 - 140 = -80 minutes.
- So, we now have -1 hour and -80 minutes.
Calculating the hours:
- Subtracting 1 hour from 4 hours gives us 4 - 1 = 3 hours.
Converting the hours:
- Since we have a negative result for the hours, we need to borrow 1 day from the day section.
- Subtracting 3 hours from 24 hours gives us 24 - 3 = 21 hours.
Final result:
The time that is 3 hours before 4:40 a.m. is 1:40 a.m.
