To solve the given expression, let's perform the calculations step by step:

Step 1: Add the hours and minutes separately. 4 hours + 2 hours = 6 hours 58 minutes + 17 minutes = 75 minutes

Step 2: Convert the excess minutes to hours if needed. Since 75 minutes is greater than 60 minutes, we can convert it to 1 hour and 15 minutes. So, we add 1 hour to the previous result: 6 hours + 1 hour = 7 hours 75 minutes - 60 minutes = 15 minutes

Step 3: Subtract the next set of hours and minutes. 7 hours - 3 hours = 4 hours 15 minutes - 29 minutes = -14 minutes

Step 4: Adjust the negative minutes by converting them to hours. Since we have -14 minutes, we can convert it to -1 hour and 14 minutes. So, we subtract 1 hour from the previous result: 4 hours - 1 hour = 3 hours -14 minutes + 60 minutes = 46 minutes

Step 5: Subtract the next set of minutes and seconds. 46 minutes - 7 minutes = 39 minutes 9 seconds - 46 seconds = -37 seconds

Step 6: Adjust the negative seconds by converting them to minutes. Since we have -37 seconds, we can convert it to -1 minute and 37 seconds. So, we subtract 1 minute from the previous result: 39 minutes - 1 minute = 38 minutes -37 seconds + 60 seconds = 23 seconds

Step 7: Add the final set of minutes and seconds. 38 minutes + 48 minutes = 86 minutes 23 seconds + 35 seconds = 58 seconds

The final result is 3 hours 86 minutes 58 seconds.
