Question

A field trip group arrived at the museum to watch a 45 minute video they spent two and half hours looking at the displays they left at 12:15 pm what time did they arrive

Answer 1

If this problem is stating that the group watched the 45-minute video and then spent an additional 2.5 hours looking at displays, then the group was at the museum for a total of how many minutes?

1 hour = 60 minutes
2.5 hours = 60 * 2.5 = 150 minutes

total amount of time the group was at the museum = 45 + 150 = 195 minutes

195/60 = 3 15/60 = 3 hours and 15 minutes

If the group left at 12:15 p.m., then we need to determine what time it was 3 hours and 15 minutes prior to 12:15 p.m.

12:15 p.m. - 3:15 (3 hours and 15 minutes) = 9:00 a.m.
