Answer 3

Let's break down the calculations step by step:

1. 2 hours 47 minutes + 5 hours 40 minutes = (2 hours + 5 hours) + (47 minutes + 40 minutes) = 7 hours + 87 minutes

2. 7 hours + 87 minutes + 28 hours 10 minutes = (7 hours + 28 hours) + (87 minutes + 10 minutes) = 35 hours + 97 minutes

3. 35 hours + 97 minutes - 4 hours 10 minutes = (35 hours - 4 hours) + (97 minutes - 10 minutes) = 31 hours + 87 minutes

4. 2 hours 49 minutes × 10 = 2 hours × 10 + 49 minutes × 10 = 20 hours + 490 minutes

5. 20 hours + 490 minutes ÷ 3 = 20 hours + (490 minutes ÷ 3) = 20 hours + 163.33 minutes (rounded to two decimal places)

Now, we need to convert the minutes to hours by dividing by 60:

163.33 minutes ÷ 60 = 2.72 hours (rounded to two decimal places)

So, the final result is:

31 hours + 2.72 hours = 33.72 hours

You can also express this as 33 hours and 43.2 minutes by converting the remaining 0.72 hours to minutes (0.72 hours * 60 minutes/hour = 43.2 minutes).
