Question

How do you solve this someone help please

Answer 1

The film lasted until 8:27.

This is true because 102 minutes is 1 hour and 42 minutes. If you add 1 hour and 42 minutes onto 6 hours and 45 minutes, the beginning time then. You would get 8 hours and 27 minutes.

This is my equation. ---->
  6:45
+1:42
_____
   7:87 <---- But that isn't correct because 87 minutes is over an hour.  

So if you do the correct numbers you would get 8:27 as your answer! 

HOPE I HELPED!!! :D
