Answer:
• Most odometers work by counting wheel rotations and assume that the distance traveled is the number of wheel rotations times the tire circumference, which is a standard tire diameter times pi (3.1416). Odometer errors are typically proportional to speedometer errors.
• When the engine turns over, the driveshaft turns to make the wheels spin round. The speedometer cable, powered by the driveshaft, turns as well. The cable spins a magnet around at the same speed inside the speed cup. As the speed cup turns, it turns the pointer up the dial, indicating the car's speed.
