The Winter Festival is well underway and BrainBashers control is working out the plane times for the return journeys.
Unfortunately, the BrainBashers timetable software is playing up again and has worked out the times incorrectly, as shown below.
France 4.00pm
Mexico 3.00pm
Jamaica 5.00pm
Japan 1.00pm
According to the software, at what time is the return trip to Finland?
