Here is your new problem of the week! You have one week from today to respond. Remember, you will not see your responses until the time is up (to avoid seeing other people's answers).

Good luck!

How Much Time?

School begins in your classroom at 7:55 am each day. On Monday, you leave your classroom for gym at 10:45 and return at 11:13, leave for lunch at 11:27 and return at 11:54, leave for recess at 12:31 and return at 12:56, and leave for music at 2:05 and return at 2:28. If school ends at 3:05, how much time (in hours and minutes – such as 4 hours 25 minutes) do you spend in your classroom on Monday?
