Question

9 ч 45 мин + 12 ч 36 мин − 5 ч 19 мин = ч мин

Answer 1

=16ч+(45+36-19) мин=17час 2мин

Answer 2

To solve the given expression, add the first two time intervals and then subtract the third time interval:

9 hours 45 minutes + 12 hours 36 minutes - 5 hours 19 minutes

Step 1: Add the first two time intervals: (9 hours + 12 hours) + (45 minutes + 36 minutes) = 21 hours + 81 minutes

Step 2: Convert 81 minutes to hours and minutes: 81 minutes ÷ 60 minutes/hour = 1 hour 21 minutes

Now, we have: 21 hours + 1 hour 21 minutes

Step 3: Add the hours and minutes separately: 21 hours + 1 hour = 22 hours 21 minutes

So, the result is 22 hours and 21 minutes.
