1. The speed of light is 300,000,000 meters per second. How far is that in kilometers ? (3x108 m/s) 3x1011 3x107 3x105 3x1012

10. 2. A radio transmission from the Apollo lander on the moon took 2 seconds to reach Earth. How far is the moon from Earth? (3x108 m/s) 300,000km 600,000,000km 3x108 m/s 6x108 m 3x1016 m

11. 3. Earth is 1 Astronomical units from the Sun, or 8. 3 light minutes
3. Earth is 1 Astronomical units from the Sun, or 8.3 light minutes. Mars is 12.7 light minutes from the Sun. How many AU’s is that?

12. 4. An astronomical unit equals 150 million kilometers
4. An astronomical unit equals 150 million kilometers. Light moves at 300,000,000 m/s, so it would take light how long to go 1 AU in seconds?
