Answer 3

To subtract the two given times:

Step 1: Convert both times to a common format (minutes or hours). Step 2: Subtract the two times.

Let's start with Step 1:

17 hours 20 minutes = 17 * 60 + 20 = 1040 minutes 15 hours 40 minutes = 15 * 60 + 40 = 940 minutes

Now, move on to Step 2:

1040 minutes - 940 minutes = 100 minutes

So, 17 hours 20 minutes - 15 hours 40 minutes = 100 minutes.

However, 100 minutes can also be expressed as 1 hour and 40 minutes, since 60 minutes make up 1 hour.

Therefore, the final result is 1 hour 40 minutes.
