The answer depends on the units in which the speed of light is given as 3.00
-- The distance that light travels in some amount of time is expressed in units of distance. -- The time that it takes light to cover some amount of distance is expressed in units of time. -- The speed of light is expressed in units of speed . . . distance/time
The speed of light is equal to 1 unit of c, where c is the speed of light in a vacuum, approximately 299,792 kilometers per second.

Refractive index is a dimensionless quantity because it is the ratio of the speed of light in a vacuum to the speed of light in a medium. Since it is a ratio of two similar quantities, it does not have any units.
You do not state the units. The speed of light is 300,000 kilometres per second, or 186,000 miles per second.
1.5 no units (APEX)
1 AU is approximately 8 light minutes.
The index of refraction is a dimensionless quantity representing how much light bends as it passes through a medium compared to a vacuum. It is a ratio of the speed of light in a vacuum to the speed of light in the medium, so the units cancel out, leaving a unitless value.
In the equation Emc2, the units of energy are joules (J), mass is in kilograms (kg), and the speed of light is approximately 3.00 x 108 meters per second (m/s).
