If you have an old style speedometer and odometer (not digital), then it is probably the speedometer cable that broke. Not too hard to fix, but it does run from the transmission to behind the dash. Sometimes difficult to reach up under the dash to remove it.
If it's a digital speedometer and odometer, then it is probably an ABS speed sensor that is defective. The speed sensor could be dirty or defective. You should have at least two on your car, one behind each of the front rotors. They are very expensive, though. Around $150 each at Autozone.
I have added a photo of what they look like for your car.
