Brooke's class took a field trip to the art museum. They left school at 11:04 A.M. It took them 1 hour and 19 minutes to drive to the museum. They stayed at the museum for 3 hours and 41 minutes. What time was it when Brooke's class left the museum?

Answers

Answer:

11.30am

Step-by-step explanation:

They time he left equal to the time he came

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.
