Do the Trains Run On Time?

The trains in Clarksville tend to be a little lackadaisical in performance. Plus, the good citizens of Clarksville have forgotten to update the train schedule. The trains are supposed to run every 2 hours, but they actually run every 2.5 hours.

Trina is a visitor to the village, and unaware of this little problem. She expects to catch a train at 7:00 p.m., since that's what the schedule told her, and she arrived at the station at 6:45 p.m.

The first train of the day was supposed to leave at 5 a.m. but it actually left at 5:30 a.m. All of the other trains ran 2.5 hours apart after this one.

Trina is going to catch the next train that arrives. What time will she actually catch her train?
