Hi!
I assume you ask because of the “20min rule”.
Traveling time is calculated as follows: The actually time on the foot / road / rail plus half of the frequency of the line for each line change (it is assumed that when somebody exchanges at a stop not knowing when a vehicle arrives the average will be half of the frequency).
But at the first stop only a quarter of the frequency will be added to the total time (assuming somebody goes to a stop knowing when vehicles depart).
So in the case of your example this will result in a waiting time of about 11 minutes, leaving 9 minutes for traveling.
Best regards
Tom
