Answer: 07:54
Step-by-step explanation: First, let's subtract the hours:
19 - 11 = 8
Now we can subtract the times:
19 - 25 = ?
You may notice that the answer to this problem would be negative. Well, we can first find what we have to take away from 19 to get to 0.
19 - 19 = 0
We still have our 6 left! (From subtracting 25 - 6 so we could subtract 19 from 19.) Well, now we can just think about the hour below 8: 7. If we go into the negatives, that is the same as going one hour down. So:
07:??
Let's subtract our six. Remember, once you drop an hour, you have to start from 60 minutes again; you subtract 6 from 60:
60 - 6 = 54
07:54
