Answer 2

To calculate the result of the given time expressions, we'll perform the addition and subtraction operations step by step:

1. Convert all the times to seconds: 15 minutes = 15 * 60 seconds = 900 seconds 3 minutes 49 seconds = 3 * 60 + 49 = 229 seconds 26 minutes 52 seconds = 26 * 60 + 52 = 1612 seconds

2. Perform the addition and subtraction: 900 seconds - 229 seconds + 1612 seconds = 2283 seconds

3. Convert the result back to minutes and seconds: 2283 seconds ÷ 60 seconds/minute = 38 minutes with a remainder of 3 seconds

So, the final result is 38 minutes and 3 seconds.
