Answer 2

Answer:

$= > 3 \times{10}^{7} \: meter \: per \: second \\ = > 10.8 \: kilometer \: per \: hour \: \:$

The speed of light is calculated to be 299,792,458m/s. Often equated to 3*10^8 m/s as it makes our calculations very easy.

But, the one-way speed of light(from source to object only) has never been practically measured. All those are theoretical calculations.

Whereas the two-way speed ( from source to object and then back to the source) of light has been practically measured and is then divided by two to calculate the one-way speed of light.

The problem with practically calculating the one-way speed of light is that we cannot synchronize clocks accurately.
