Answer 2

To calculate the result of the expression, let's perform the subtraction first and then the addition:

1. Subtract: 18 minutes 9 seconds - 7 minutes 46 seconds Convert everything to seconds for easier calculation: (18 minutes * 60 seconds/minute) + 9 seconds = 1089 seconds (7 minutes * 60 seconds/minute) + 46 seconds = 466 seconds

   Now, perform the subtraction: 1089 seconds - 466 seconds = 623 seconds

2. Add: 623 seconds + 48 minutes 35 seconds Convert 48 minutes to seconds: 48 minutes * 60 seconds/minute = 2880 seconds

   Now, perform the addition: 623 seconds + 2880 seconds = 3503 seconds

Finally, convert the total seconds back to minutes and seconds:

3503 seconds = 58 minutes 23 seconds

So, the result is 58 minutes 23 seconds.
