About city competition.

how the choice of cities for the competition works?

• ## Chapter 4

R: 3 Change the motor and pay \$12000

First thing to do is calculate how long it will be the journey:

620km at 300Km/h - 2h and 2min

1 - they will arrive after midnight - 4h (delay) + 2,02h = 6,02h

if they start at 6.30pm they arrive at 00.32am- a lot of costs -

2 - Lot of costs

3 - motor repair - and 90min delay - 1,5h (delay) + 2,02h = 3,52h

If thet start at 6.30pm they arrive at 10.28pm

4 - 40% of the speed represents a speed of 120km/h so, to make 620km they will spend 310min about 5,17h in journey.

If they start at 6.30pm they arrive at 11.47pm

So, if it was me, i will protect the customers and myself. The motor it will always be repaired so the costsof \$12.000 are in both situations.

It gives a better journey for customers, less stress, with less risk of other problem that will make the arriving after midninght...

If you are in a situation, that you have to risk, you dont have the \$12.000 to pay repair, so if they arrive after midnight you cannot refund.... good luck with your life
