We all except the standard model of the velocity of light speed is a linear motion of 186,000km/s. ( or just under 300,000km/s ). If we do the math's we can project the time in a kilometer. Any body into math's realizes reciprocals are only a mater of 1 dived any number. Take 60 for example.

1 dived 60 is 60th. If we multiply  60th by 60 brings us back to 1 respectively. Math's can't lie you know. Thus 60 and 60th are reciprocals of each other. It applies to any number.

Operating on the principle of 300,000km/s, the reciprocal  is 300,000th second light travels a kilometer. Prove when we multiply 300,00th by 300,000 brings us back to a second.

When we say  "One thousand and one" it is the time the second hand of analogue wall clocks and wrist and stop watches move a division and the second pause of digital time pieces that we can be prey good at judging we walked a meter in that time. Mathematics projects by that time light had traveled a distance of just under 300,000km.

So far we know there is a 1,000 meters in a kilometer. This means there is 300, 000,000m' ( million meters ) in 300,000km. Thus light had traveled a distance of 300,000,000m' the same time we walked a meter mathematics projects the equivalent of traveling round the circumference of the earth just under 7 times in the same time.

If we take the reciprocal of 300 million meters in a second light had traveled a distance of a meter in 300,millionth of a second  or given the standard metric prefix unit micro 300 microseconds. Mathematics proves this when we multiply 300 millionth ( or 3 microseconds ) by 300 million equals is a second. In other words light travels a 300 million 1 meter increments in a second.

We can apply the same math's to deduce the time light travels a centimeter, a millimeter, or a micrometer and smaller. The laws of mathematics tells us it is only a matter of adding 3 zeros onto each successive smaller value and so on. For example light travels 300,000 millionth  second in a centimeter and 300,000,000,000,000 millionth ( or becomes a billionth ) second in a millimeter or 3, billionth second in a micrometer respectively.

A quantum physics idea light jumps ( or quantum leaps ) a distance of 300,000km increments every second. It is the maximum distance. It can't jump any further in that time.
