Answer:
7 hours 35 minutes
Step-by-step explanation:
You want to know the length of the time period between 1:29 pm and 9:04 pm.
Hours
Remembering that an hour is 60 minutes, we can rewrite the ending time before we subtract the beginning time.
9:04 -1:29
= 8:64 -1:29 = (8-1):(64-29) = 7:35
The movie marathon lasted 7 hours 35 minutes.
