Exercise
Let's do some maths about transport new prices in Stockholm!
We know that:
- Stockholm is divided in three areas named A, B and C;
- Sollentuna is in B and Solna in A;
- A trip within a same zone costs 1 ticket, 2 tickets for two zones, 3 for three;
- If you buy a ticket book, one ticket costs 10sek.
1 - In theory, how much should you pay to travel back and forth Sollentuna to Solna?
2 - Guess how much your favourite MeLu really spent if:
- You need to change from bus to subway (or subway to bus) in Kista (in zone A);
- The bus driver on the way back doesn't care about your subway ticket;
- The previous ticket book makes you have a ticket at 18sek (and the difference with the new price is not considered).
3 - How should our traveller react?
The solution in the next few days, but I'm waiting for your answers and reactions in the comments!
Note: A trip within a same zone costs 2 tickets, 3 tickets for two zones and 4 tickets for three.
