A city train travels on double circle rails having a main station and stations 1 – 8 in this order. There are two trains: Train A and train B. Train A travels clockwise and stops only at odd numbered stations and the main station. Train B travels counterclockwise and stops only at even numbered stations and the main station. Only at the main station the travelers can switch one train for another.
Michael travels from station 5 to station 6, Sarah from station 7 to station 4, and Liza from station 2 to station 5. a) How many times do they totally travel between stations 5 to 6? b) Which station of 1 to 8 is passed maximum number of times? How many times? “Passed” means that the train passes a station without stopping or the traveler doesn´t get out of the train even though the train stops
P.S: I am preparing for my entrance exam and I found this question on my sample paper and have no clue how to verify my answer. This is what I have tried and my answers are:
2) three times on station 8 not 7.
*Micheal travels: 5-7-Station A-8-6
Sarah: 7-Station A-8-6-4
