Your trolley jumped the rails entirely. Mismatch may well serve as a
reason for this too. Consider:
A train traveling 89mph left Cincinnati at 12PM. An airplane flew out
of Denver at 12:10PM going in the same direction. When will they dock
at the same time in Seattle if they are in transit and Daylight
Savings makes its changeover next month?

For complete credit:
What day did the train leave?
What day did the airplane arrive?
