The movie takes 98 minutes. You watched it till the end and it end up at 1:13. When did the movie start

There are 60 minutes in 1 hour.
98 minutes = 1 hour and (98 - 60) minutes
98 minutes = 1 hour and 38 minutes

End time: 1:13
Duration: 1 hour 38 minutes

To subtract 1 hour 38 minutes from 1:13:
First, subtract 1 hour from 1:13, which gives 0:13 (or 12:13 from the previous hour).
Now, we need to subtract 38 minutes from 0:13.
Since 13 minutes is less than 38 minutes, we need to borrow an hour from the "0" hour, making it 12:00 and adding 60 minutes to the 13 minutes.
So, 0:13 becomes 12:00 + 13 minutes = 12:13.
Now subtract 38 minutes from 12:13:
12 hours 13 minutes - 38 minutes
= 11 hours (60 + 13) minutes - 38 minutes
= 11 hours 73 minutes - 38 minutes
= 11 hours 35 minutes

So, the movie started at 11:35.
(If 1:13 was AM, the movie started at 11:35 PM the previous day. If 1:13 was PM, the movie started at 11:35 AM on the same day.)

The movie started at 11:35.
