Answer:
14.25 Hours ( 14 Hours and 15 Minutes)
Step-by-step explanation:
Monday = 7 Hours and 25 Minutes
Tuesday = 6 Hours and 50 Minutes
First, Let's add 7 and 6 which is 13 Hours
Then 25 + 50 Minutes = 75 Minutes Which is also 1 Hours and 15 Minutes.
1 Hour = 60 Minutes
Hence, 75 - 60 = 15
Therefore it 1 Hours and 15 Minutes...
Next, 13 Hours + 1 Hours and 15 Minutes =
14 Hours and 15 Minutes..
thus, 14 Hours and 15 Minutes which is also 14.25 Hour is the average number of hours she spent in school.
