Don’t you know I’m still standing better than I ever did –
Looking like a true survivor, feeling like a little kid –
I’m still standing after all this time –

In a physics forum it was about representing speed.
v = s/t.
Velocity is the distance travelled divided by time elapsed. (v – speed; s – distance; t – time).
The higher the value (v), the faster the distance travelled.
Since one participant in this discussion made a mistake with the formula and interchanged s and t, he did not represent the speed.
The reverse would be the time spent while travelling: v = t/s.
Here v is the time consumed for the distance travelled.
The higher this value (v), the slower the distance was covered.
For an object at rest (distance travelled = 0) this means a division by ZERO and this is not defined.
Surely, this means that you should always be in motion, otherwise you don’t exist or mathematically you are simply infinity like a black hole!
In the example above, you can use 30km/0h, but it is physically wrong. Because you cannot travel from a to b in ZERO time. You always need a time. Since the speed of light is the fastest speed, there is no need to think about it: it is simply not physically feasible. In the example below, however, you can use ZERO. Because you can sit, lie or stand for an hour.
Funny thing, mathematics sometimes. Isn’t it?
