Our meeting started at 9:45 a. m. and ended at 12:45 p. m. how long did the meeting take in minutes

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 = 180 minutes (this is the answer)
