Question 323000: According to the Einstein’s Theory of Relativity, nothing in the universe as we presently know it can exceed the speed of light; in a sense, it is the ultimate cosmic speed limit. Speed of light in vacuum is 300,000 kilometers/second or 671,080,888 miles/hour! Take a moment and think about this tremendously high speed; it is extremely fast; faster than a speeding bullet (speed of a rifle bullet is in the range 400 to 3,350 miles/hour). a) Show the speed of light in scientific notation in units of miles/hr. b) Given that Moon on average is 240,000 miles away from where you are standing on Earth, how long does it take a light ray to travel from the Earth to the Moon?

b) Given that Moon on average is 240,000 miles away from where you are standing on Earth, how long does it take a light ray to travel from the Earth to the Moon?
:
Convert to miles per second
 = 186,411.358 mi/sec
:
 = 1.287 sec
