correct in saying that my speedometer and odometer are 5% fast. If so if my speedometer says 50 I am actually doing 55, if it says 100 I am doing 110. Correct me if I am wrong.
Can a dealer correct the speedometer?
If you odometer is saying you went 2.1 miles when you actually went 2 miles, then the speedometer is indicating you're going faster than you really are; when it says 55 you're only going 52.75 (55-5%). If it says 100, you're actually going 95.
rate = time * distance
If the distance is indicating too far (it shows 2.1 when it should show 2.0), the rate must be indicating too high (indicating 55 when it should indicate 52.75).
