Answer 3

To calculate the result, we first need to convert all the time values to a common unit, such as minutes. Then we can perform the addition and subtraction operations. Here's the step-by-step calculation:

1. Convert each time value to minutes:

   • 21 hours = 21 * 60 = 1260 minutes
   • 15 minutes = 15 minutes
   • 6 hours = 6 * 60 = 360 minutes
   • 49 minutes = 49 minutes
   • 1 day = 1 * 24 * 60 = 1440 minutes

2. Perform the addition and subtraction: 1260 minutes + 15 minutes + 360 minutes + 49 minutes - 1440 minutes

3. Combine the minutes: 1260 + 15 + 360 + 49 - 1440 = 244

The result is 244 minutes. Now, we can convert this back to hours and minutes:

244 minutes ÷ 60 = 4 hours with a remainder of 4 minutes.

So, the final result is 4 hours and 4 minutes.
