Answer:
180 minutes
Step-by-step explanation:
The problem above needs "conversion of units" from hour to minutes. Remember that: 1 hour = 60 minutes
So, if the meeting started at 9:45 a.m. and ended at 12:45 p.m., then the meeting's duration is 3 hours.
The next step is to convert 3 hours to minutes since the problem is asking for the answer in minutes.
So, 3 hours x [tex]\frac{60 minutes}{1 hour}[/tex] = 180 minutes (this is the answer)
