Homework Help: Light ray travel

  1. Oct 17, 2006 #1
    HELP-HOMEWORK...Hi, I have homework that ask "Using the velocity of light find an approximate value for the amount of time that it takes a light ray to travel from the sun to the earth." Now I know the distance between the earth and the sun is 93 million miles but I'm not catching on to the question can anyone shed some light for me.(pun intended)

    Answer this question first: How long does it take you to drive 25 miles at 25 miles an hour? I bet you know that. Well, your question is the same. You got the velocity (182,000 miles a second -- instead of 25 miles an hour), you have the distance (93 million miles -- instead of 25 miles). Solve it.
