Answer 3

To calculate the result of the given time expression, follow these steps:

Step 1: Convert all the times to minutes. 12 hours = 12 * 60 = 720 minutes 9 hours 40 minutes = 9 * 60 + 40 = 580 minutes 6 hours 50 minutes = 6 * 60 + 50 = 410 minutes

Step 2: Perform the arithmetic operations. Result = 720 minutes - 580 minutes + 410 minutes Result = 150 minutes

Step 3: Convert the result back to hours and minutes. 150 minutes = 2 hours 30 minutes

So, the final result is 2 hours and 30 minutes.
