To do this, answer each of the following with a brief explanation of the mathematics used to get there. The speed of light is 3*10^8 m/s (aka 300,000,000 meters per second). What is the speed of light in centimeters per second, kilometers per second, and miles per hour? (Hint: there are roughly 1.6 km per mile and 3600 seconds per hour) Remember to show the math; If light from the closest star to our solar system takes about 4.2 years to get to us, how far away is that star in units of Gm (aka Gigameters)? Again, explain your work.
For this short response assignment, your job is to demonstrate your understanding of SI units and how they can be applied on an astronomical scale.
