Answer 2

To calculate the total time, we need to perform arithmetic operations with hours and minutes separately. Let's do the math:

(6 hours + 5 hours) = 11 hours (18 minutes + 57 minutes) = 75 minutes

Now, let's handle the minutes. Since there are 60 minutes in an hour, we can convert the total minutes (75) to hours and minutes.

75 minutes ÷ 60 minutes/hour = 1 hour and 15 minutes

Now, we can add the hours and minutes:

11 hours + 1 hour = 12 hours 15 minutes = 15 minutes

So, the total time is 12 hours and 15 minutes.
