    Measurments

    Question 1:
    How many cubic feet of salt water are in a container that weighs one ton? One cubic foot of water weighs 64 pounds (ignore weight of the container).
    The answer is 31.25 gal.

    I tried to figure it out but the best answer I can get is 32. I don't know which conversion factor to begin.

    Question 2:
    IF the speed of light is 186,000 mile per second, how long (in hours) does it take the light from the sun to reach the planet Pluto, if it is 2,763,000,000 miles from the sun?

    Answer is: 4.13 hr (rounded)

    Am I suppose to convert the distance to time? If so, how do I go about doing that.

    Thank you,
    - Joe

    1. A ton is 2000 lbs right? So how many times will 64 go into 2000?

    2. 2,763,000,000 divided by 186,000 will give the answer in seconds. You can convert to hours, no?

    Wow, I feel so inadequate. I made the problems so much more diffucult then it should have been.

    After looking at your advice I ended up getting the correct answers. Once again thank you. Now it's time to take the quiz.
