Question

19ч42мин+20ч36мин 11ч35мин+18 ч 41 мин

Answer 1

Пошаговое объяснение:

1) 19ч 42мин + 20ч 36 мин = 19ч + 20ч = 39ч + (42мин + 36мин) = 40ч 18 мин

2) 11ч 35мин + 18ч 41мин = 11ч + 18ч = 29ч + (35мин + 41мин) = 30ч 16 мин

Answer 2

To add these times together, you can follow these steps:

1. Convert the minutes to hours if necessary. In this case, all the given times are already in hours and minutes.

2. Add the hours and minutes separately.

19 hours + 20 hours = 39 hours 42 minutes + 36 minutes = 78 minutes

11 hours + 18 hours = 29 hours 35 minutes + 41 minutes = 76 minutes

3. Convert any excess minutes to hours if necessary. In this case, 78 minutes and 76 minutes exceed 60 minutes each, so we need to convert them to hours.

78 minutes ÷ 60 minutes = 1 hour and 18 minutes 76 minutes ÷ 60 minutes = 1 hour and 16 minutes

4. Add the hours and minutes obtained in step 3 to the total hours obtained in step 2.

39 hours + 1 hour = 40 hours 29 hours + 1 hour = 30 hours

18 minutes + 16 minutes = 34 minutes

So the final result is: 40 hours 34 minutes
