Solution
Solution Steps
Step 1: Identify the Concept
The question is about the fastest motion that can be measured in any frame of reference. This refers to the speed of light in a vacuum, which is a fundamental constant in physics.
Step 2: Recall the Speed of Light
The speed of light in a vacuum is approximately \( 299,792 \, \text{km/s} \), which is often rounded to \( 300,000 \, \text{km/s} \).
Step 3: Match with Given Options
Compare the known speed of light with the options provided:
\( 300,000 \, \text{m/s} \) is incorrect as it is too slow.
\( 186,000 \, \text{km/s} \) is incorrect as it is not the standard approximation.
\( 300,000 \, \text{km/s} \) matches the standard approximation of the speed of light.
\( 186,000 \, \text{m/s} \) is incorrect as it is too slow.
Step 4: Select the Correct Option
The correct option is \( 300,000 \, \text{km/s} \), which represents the speed of light in a vacuum.
