Answer:143 minutes. Step-by-step explanation:To find out how many minutes are in 2 hours and 23 minutes, you need to convert the hours into minutes and then add the extra minutes.There are 60 minutes in one hour. So, for 2 hours, you multiply 2 by 60, which equals 120 minutes.you then add the 23 minutes to the 120 minutes you already have.So, 120 minutes (from the 2 hours) + 23 minutes = 143 minutes in total.Therefore, there are 143 minutes in 2 hours and 23 minutes.
