TACHYMETER

The tachymeter is the device which measures the speed of an automobile. Knowing
is how many seconds the car covers a distance of 1km, the meter can measure the
approximate average speed per hour during a journey (up to the maximum measurable
range of tachymeter is 60 seconds.)
If the chronograph is started at the same time as measurement, and stopped after
1 km, the average speed per hour can be determined according to the position of the
second hand. If the car covers the distance of 1km in 45second, the average hourly
speed during the journey will be about 80 km.
