. 
How far did it travel?
~~~~~~~~~~~~~~~~~~
Assuming that there was NO time change between time zones of departure and destination, we may 
conclude that the travel time was 5 + 9 = 14 hours.
Then the travel distance is the product of the average rate by elapsed time 
    distance = 60 * 14 = 840 kilometers.    ANSWER
