You start out in honeycomb 1. For all journeys along your line within honeycomb 1, tariff level 1 applies.

For a journey into honeycomb 2, tariff level 2 will apply.

When you continue your journey you reach honeycomb 3 which would be the third honeycomb you travel through.

Now you can easily determine the fare. Three honeycombs along your line = tariff level 3 = EUR 3.10 for a single ride ticket.
