Figure 1: Engine and tires and brakes, oh my!

As the lead design engineer on a car racing team, you’ve been hired to build a car that can complete a racecourse in the fastest time. To get a feel for how each component performs, you’ve built several sample car configurations with varying engines, tires, transmissions, and brakes and then tested them on the racetrack. Each combination of parts has yielded different speed results, as shown in Table 1.

There are three types of each component that you can choose from. You must pick exactly one component from each category: engine, tires, transmission and brakes.


What combination of engine, tires, transmission and brakes will give you the fastest car?
