The correct answer is B. 6 hours and 40 minutes
Explanation:
The average of a group of values refers to the middle or "average" value of these. This mathematical factor can be calculated by adding all the values, in this case you need to dd the time Ryan slept each night, and then divide the total into the 5 nights. Below, you can find the process.
1. First add all the hours
6 + 5 + 7 + 6 + 7= 31 hours
2. Add the minutes
20 + 50 + 5 + 47 +18 = 140 minutes
3. Divide the result of the minutes into 60 to convert part of these minutes to hours.
140 / 60 = 2.3333 - There are 2 hours in the total of minutes and 20 minutes (0.3333 x 60 minutes = 20 minutes)
4. Total of hours = 31 + 2 = 33 hours
Total of minutes = 20 minutes
5. Divide the total into 5 days
33 hours 20 minutes = 5 days
33 / 5 = 6.6 hours that represent 6 hours and 36 minutes (0.6 x 60 = 36 minutes)
20 minutes / 5 days = 4 minutes
Total: 6 hours and 40 minutes (36 minutes + 4 minutes)
