That formular is wrong. The correct formular is (according to the official TÜV theory test questions):
2x(v/10)x3 (well technically they only calculate it for 1 second so I added the 2 infront).
That is, at the same time, slightly more than half your speed meters.
Your formula looks like the formular for the "Bremsweg" with a "2x" added infront but thats not how it works because time is not a variable there...
Wait no. So I'm Shure I got the Formular wrong, but there is one that is specifically for the distance covered per second. And of course time is a cariable because how else would you define speed.
Yeah, that formular "(v/10)x3" gives you the meters you travel in one second.
Your speedometer tells you how many km you travel per hour (km/h) and using that conversion you get the meters you travel per second (m/s).
