Let's calculate the time when Brooke's class left the museum. They spent 3 hours and 41 minutes at the museum, so if we add that to the time they arrived, we'll get the departure time.
They arrived at the museum 1 hour and 19 minutes after leaving school at 11:04 A.M. To calculate the arrival time, we add 1 hour and 19 minutes to 11:04 A.M.
11:04 A.M. + 1 hour and 19 minutes = 12:23 P.M.
Now, if we add the 3 hours and 41 minutes they spent at the museum to the arrival time of 12:23 P.M., we can find the departure time.
12:23 P.M. + 3 hours and 41 minutes = 4:04 P.M.
So, Brooke's class left the museum at 4:04 P.M.
