Answer:
4:35 pm
Explanation:
We are given the time that a movie ends, the duration of the movie, and we are asked to find the start time. Therefore, we just need to subtract the duration from the end time, and we'll have the start time.
First, we subtract the 3 hours from 8:15 pm, and that is 5:15.
*Remember that the minutes counter resets at 60*
Then we just subtract the 40 minutes, which means we end at 4:35.
