Fair labour hours for small-medium accident repair? on 2004 Toyota RAV4

I recently received the bill for an accident we caused (rear-ended the car in front of us at about 10-20km/h); it was relatively minor, with the 2011 Accord boot we hit being crumpled several inches fairly evenly across its length - it's hard to describe more accurately. we didn't have insurance at the time, so we're paying the $5600 out of our pockets. I was looking at the detailed invoice for a price breakdown, and noticed that labour was counted at 90 hours' worth. That's two full-time weeks' work for a crumpled rear end. is this a fair labour amount for that kind of work? I'm not in the industry, so I have no idea what is normal. If anyone has any knowledge or thought, it'd be much appreciated!
