How long is each chapter?

How long is each chapter? My friend and I (we are playing it together technically cuse I'm sharing my screen on discord and we are sharing the voices and doing the mystery, etc) just finished chapter 1 last night and we have already played for 13.5 hours. So I was just wondering if we can expect every chapter to take that long, I hope not, we have lives, lol (granted, subtract a couple hours for the prologue, but that's still a lot)

7-9 hrs for me
Roughly 3-5 hours for exploration and free time events, 1hr for crime investigation and 2-3 hours for the trial
It's definitely longer than danganronpa 1
