    300km/h = 620km in 2hrs 4 mins. To arrive by midnight need to leave by 9:56


    1. 4hr delay = 10:30 leave - miss connection $8,000 compensation + $30,000 hotel = $38,000

    2. full refund = $16,000

    3. 90 min delay = 8pm leave so make connection, new motor $12,000

    4. 40% of 300km/h = 120 km/h = 620km in 5hrs 10 min can make connection at no cost

    for price 20$ score 3, 40$ score 2, 20$ score 1 with a weighting factor of 2

    for durability high score 3, average score 2, low score 1 with a weighting factor of 4


    This gives

    Mecha Heads a score of 10

    Swiss Metal a score of 14

    General Machines a score of 12


    Swiss metal would be preferred as the highest score with no other supplier better than them on punctuality

  • Chapter 1

    at 14km/h in 30 min supervisor can cover 7km which is more than the 6.3km to the switch

    so Yes.
