Avery‘s parents have a limited her phone time to 3 hours a day. if she’s up for 12 hours a day, how many minutes per hour can she be on her phone?

15 minutes per hour

Step-by-step explanation:

Given that:

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.
