13 ч 18 мин+8 ч 52 мин=798 мин+532 мин=1330 мин= 22 ч 10 мин

Answer 2

To solve the given arithmetic expression:

11 hours 26 minutes - 3 hours 48 minutes = 12 days 8 hours - 6 days 19 hours

To simplify this, we need to convert days and hours to a unified format (hours). Since a day consists of 24 hours:

11 hours 26 minutes - 3 hours 48 minutes = (12 days * 24 hours + 8 hours) - (6 days * 24 hours + 19 hours)

= (288 hours + 8 hours) - (144 hours + 19 hours)

= 296 hours - 163 hours

= 133 hours

Next part of the expression:

13 hours 18 minutes + 8 hours 52 minutes

= (13 hours + 8 hours) + (18 minutes + 52 minutes)

= 21 hours + 70 minutes

Since 60 minutes make up 1 hour, we can convert 70 minutes to hours by dividing by 60:

21 hours + (70 minutes / 60 hours) = 21 hours + 1.17 hours

= 22.17 hours

Therefore, the final result is 133 hours + 22.17 hours = 155.17 hours.
