Steps to Solve
- Subtract the seconds
Since 28 is less than 36, we need to borrow 1 minute (60 seconds) from the minutes column.
$28 + 60 = 88$
Now we subtract the seconds:
$88 - 36 = 52$ seconds.
- Subtract the minutes
Since we borrowed 1 minute from the minutes column, we now have 16 minutes.
Since 16 is less than 45, we need to borrow 1 hour (60 minutes) from the hours column.
$16 + 60 = 76$
Now we subtract the minutes:
$76 - 45 = 31$ minutes.
- Subtract the hours
Since we borrowed 1 hour from the hours column, we now have 7 hours.
Subtract the hours:
$7 - 7 = 0$ hours.
- Combine the results
Combine the hours, minutes, and seconds to get the final answer.

More Information
The result represents 0 hours, 31 minutes, and 52 seconds. This is how much time has elapsed between the two given times.
Tips
A common mistake is forgetting to borrow when the seconds or minutes value being subtracted is larger than the value it's being subtracted from. Also, one might forget that when borrowing, 60 is added to the minutes/seconds column, not 100.
