This sounds more like a homework problem, but I'll give you the benefit of
the doubt.

You can start with something like this:

CARS = {
  'mustang' => [300.0, 3480],
  'camaro' => [300.0, 3780]
}

car1,car2 = ARGV

def compare car1, car2
  ratio1 = ratio car1
  ratio2 = ratio car2

  ratio1 >= ratio2 ? car1 : car2
end

def ratio car
  CARS[car][0] / CARS[car][1]
end

puts compare car1, car2
