    The best option is 4. Napping Neptune

    Napping Neptune travels at an average speed of 120 Km/h. It will cover the 620 Km in 5 hours and 10 minutes, arriving at Hicksburg at 23:40. The passengers will have enough time to make their connections.

    There is no cost for this option.

    Option 1 will result in the passengers arriving after midnight. It takes Jumbo Jupiter 2 hours 4 minutes to travel 620 Km. With the 4 hour delay caused by the repair, the passengers will arrive at 00:34. The cost will be $8,000 for the train fare compensation and $30,000 for hotel costs.

    Option 3 will also arrive in time for the connections. The repair delay added to the travel time will result in Jumbo Jupiter arriving at 22:04. This option will cost $12,000 for the new motor.

    Option 2 will cost $16,000 for reimbursement of train fares. In addition, you fail to transport any passengers to their destination.

    Starting with punctuality, the factor of least importance, the different companies are rated Mecha-Heads 3, Swiss Metal 4, General machines 4. These scores are graded out of 5.

    The other ratios (for punctuality and durability) are graded out of 3, so the raw scores will be adjusted to maintain consistency. The raw scores will be divided by 5 (stars) and multiplied by 3.

    This method gives the scores Mecha-Heads 1.8, Swiss Metal 2.4, General Machines 2.4.

    The ratio for low pricing is 3:1:2 for Mecha-Heads : Swiss Metal : General Machines.

    As pricing is twice as important as punctuality, these ratio scores will be doubled.

    Mecha-Heads scores 6, Swiss Metal scores 2, General Machines scores 4.

    Keeping the ratio 1:2:3, Mecha-Heads has a low durability so scores 1, General Machines has an average durability so scores 2 and Swiss Metal has the greatest durability so scores 3.

    As durability is twice as important as pricing, these ratio scores will be multiplied by a factor of 4.

    Mecha-Heads scores 4, Swiss Metal scores 12 and General Machines scores 8.

    Adding the scores gives Mecha-Heads a total of 11.8, Swiss Metal a total of 16.4 and General Machines a total of 14.4.

    Swiss Metal is the supplier chosen.

    Yes, the supervisor will get there first.

    The two trains have a closing speed of 280 km/h. They will cover the gap of 140 km in 30 minutes.

    Running at an average speed of 14 km/h, the supervisor would be able to run a distance of 7 km in the same 30 minutes. He only need to run for 6.3 km so he will have plenty of time to get to the manual switch first.
