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.
