Imagine you are sitting on the bus and see a sign with a number of miles to the nearest town. Here

More known as The tachymeter is used to measure the speed based on the distance you have moved, for example. the bus. Imagine you are sitting in a bus and you want to know the speed of the running - you can with tachymeter. This assumes you know how far the distance you have moved, and how long it took. Since speed is the relationship immigration news between distance and time, it is possible using the tachymeter, to judge speed using a scale. In watches with tachymeter is a scale usually on the rim of the watch, which can go from 500 to 60 scale varies from watch to watch, but they tell you all the speed you on average have moved you, based on the distance you have moved you.
Imagine you are sitting on the bus and see a sign with a number of miles to the nearest town. Here you should start your chronometer (stopwatch) and stop at the next sign, which is 1 km away. The figure from the hand, said speed - is the seconds immigration news from 100, you all run 1 km with an average of 100 km / h We mentioned earlier chronometer, which is not certain you know what is - possibly read our post about chronometer here. But to uncover chronometer quickly, immigration news it is a built-in stopwatch. It may happen you encounter watches that do not have built a chronometer, which may complicate immigration news things a bit. We will therefore look at the math behind, to give you a deeper insight into speeds. We mentioned earlier immigration news that the rate is the ratio of distance and time, which is why we call it kmh. Here, the formula for the speed:
