If x is the distance traveled the indicator on your dash tells you (outputs) x (odometer) and dx/dt (speedometer). The input is x in the form of pulses (or rotation) from the transmission.
I would suspect that since x is easily calculated and recorded there would be no adjustment to the odometer. Computing the derivative however is not so straightforward. I would suspect this (SPEEDO) could have a calibration adjustment.
If the input is wrong both outputs will be afffected but the speedometer could be calibrated correctly. Likewise if the odometer was correct the speedometer could be calibrated incorrectly
