I have to plan bus trip between point A and point B.
The time it takes to travel between A and B is 35 minutes.
I want to enable passengers from A to B and from B to A board on bus every 5 minutes.
Quiz: How many buses do I need?
If you’ve figured that out, good work! Let’s add another destination, point C which is 30 minutes away from either A or B (to keep it simple).
Quiz: How many buses would I need to keep the same 5-minute service frequency among 3 destinations?
