Answer:
15 minutes per hour
Step-by-step explanation:

Phone usage limit = 3 hours
As 1 hour = 60 mins so, 3 hours = 3 * 60 = 180 mins
Now:
Phone usage limit = 180 mins
She is up for 12 hours, So:
Minutes per hour for mobile usage = 180/12 = 15 mins per hour
So if Avery is up for 12 hours she can use her mobile phone 15 mins per hours according to given usage limit.
