A car travels at a speed of $x$ kilometers per hour on a highway, where the speed limit is between 60 and 120 kilometers per hour ($60 \leq x \leq 120$). The fuel consumption per hour is given by the formula $\frac{1}{5}(x - k + \frac{4500}{x})$ liters, where $k$ is a constant and $60 \leq k \leq 100$.

(1) If the car travels at a speed of 120 kilometers per hour and consumes 11.5 liters of fuel per hour, find the range of $x$ such that the hourly fuel consumption does not exceed 9 liters.

(2) Find the minimum fuel consumption when the car travels a distance of 100 kilometers.
