The figure below shows the possible routes from city A to city J as well as the time (in minutes) required for a trip between each pair of cities (note that if no arc joins two cities it is not possible to travel non-stop between those two cities) . A traveler wishes to find the quickest option to travel from city A to city J. 
What is the time to travel between nodes F and J?
