Answer:
225 minutes or 3 hours and 45 minutes
Step-by-step explanation:
45 (minutes per day) times 5 (days in a school week) = 225 minutes
or add 45 (minutes per day)+ 45+45+45+45 = 225
To get the hours:
Divide 225 by 60 (minutes per hour) and it is 3 - remainder 45.
You do -2 plus 4. Answer is 2.
Then do 2-(-2) which is 0.
The final answer is 2.
