Answer :
To find out what time it was 1 hour and 30 minutes ago when it is currently 3:30, you can follow these steps:
1. Start with the current time: You know that the current time is 3:30.
2. Subtract the minutes first: Since you need to go back 30 minutes, subtract 30 minutes from 30 minutes.
- This results in 0 minutes, so there's no adjustment needed for the minutes.
3. Subtract the hour next: Now, subtract 1 hour from 3:00.
- 3 - 1 = 2
4. Check for any adjustments: Since subtracting minutes resulted in 0 and the hours are still positive, no further adjustments are necessary.
Therefore, 1 hour and 30 minutes before 3:30 was 2:00.
