Final answer:
To find out the time Lena's class left the museum, add the time they spent at the museum to the time they left school. They left school at 7:13 A.M. and spent 3 hours and 35 minutes at the museum. Therefore, they left the museum at 10:50 A.M.
Explanation:
To find out what time Lena's class left the museum, we need to add the time they spent at the museum to the time they left school. We can add the time using the 24-hour clock system.
First, convert the 41 minutes to hours by dividing it by 60: 41 ÷ 60 = 0.68 hours. Next, add the 3 hours and 35 minutes to the converted hours: 3 + 0.68 = 3.68 hours.
Finally, add the calculated time to the time they left school: 7:13 + 3.68 = 10:50 A.M. Therefore, Lena's class left the museum at 10:50 A.M.
