Hello. The answer, though I don't know what options you need to be answered, is that there is less friction between the car tires and the ice, than when they are on the road. Causing the car to slide.
To calculate the wavelength, the formula to use is:
Wavelength = Speed / Frequency
Wavelength = 15 km/s / 9 Hz
Wavelength = 1.6666666667 or 1.67 km
The standard unit for Wavelength is meter so the final answer would be 1666.67 meters
