Movie starts at 7:45 and its 1hr 26 min, what time would the movie end.

well, let's split the hours to 7 and 45 minutes and 1 and 26 minutes.

adding the hours we get 7 + 1 = 8.

adding the minutes we get 45 + 26 = 71.

so the time will be 8 and 71 minutes, wait a second! 71 minutes is really 60 + 11.

so the time will be 8 hours + 60 minutes plus 11 minutes, or 8 hours + 1 hour plus 11 minutes, or 9:11.
