A gear in the transmission drives a flexible mechanical shaft that provides the rotary motion to the speedometer. It drives a dial gear that rotates with numbers 0-9 on it. This dial gear rotates the next one to the left one digit for every complete revolution it makes. This sequence repeats for all the digits.
The speedometer uses a magnet that is spun by the flexible shaft. It rotates inside an aluminum cup. The rotation creates eddy currents in the cup that apply a torque to the cup. The cup is restrained by a spring so the angular deflection is proportional to the speed of rotation of the shaft. A pointer attached to the cup indicates the speed on a dial.

The exact mileage per year is the odometer reading at the end of the year minus the odometer reading at the beginning of the year. If you don't have the odometer reading from the beginning of the year, the next best thing is to subtract an older odometer reading from the reading at the beginning of the year, then divide the difference by the number of years between readings. Without any odometer readings from the past, the best you can do is to calculate the average annual mileage over the life of the truck, which is the current odometer reading divided by the truck's years of service.
