    whats this world coming too, math problems with more letters than numbers? next we will all talk in binary code

    Why dont I throw in my physics homework in here.
    Both animals start on a line. Turtle is moving at .2m/s and the hair at 5.0m/s. In five minutes what will be the distance of the hair in m? How long will it need to wait for the turtle to catch up in s?

    Thread hijacker! But I'll help anyway: distance = rate * time. Since you have a speed/rate, and a time... you can find a distance. When you have any two of those variables, you can find the third.

    Yes Ann, I believe you do need a value on the other side of the equal sign.


    WaterKirby. Hare: 5minutes = 300s. so 5m * 300s = 1500m

    Turtle: .2m * 300s = 60m. so 1500m - 60m = 1440m. 1440m / .2m = 7200s = 120minutes, or 2 hours.

    Ok, o just checked with my dad, and you have to have the expression equal a set value if you are going to find b. I trust him a ton because he went to 12 years of college (including 7 years of medical school), majored in chemistry, minored in math , plus he did another 5th residency, so that he could have his practice, which he now has. He is a retinal specialist, and is brilliant...not to brag, but he really is. I have never missed anything on my homework, at least not anything that he helped me with, and once in a while he can prove the teacher made mistakes, and they admit it


    Anyways, onto our thread hijacker... You have to find the distance that each of the animals traveled in the five minutes. To do this, you need to find out how many seconds are in 5min. There are 300seconds in 5min. Now you take the rates they are moving at, and multiply them by 300. This will tell you how far they have each traveled in the five minutes. Now you jet need to find out how far ahead the hare is, and divide the distance left for the turtle by the turtle's speed. I have the whole answer and problem worked out, but I think you can find the answer on your own now.

    Well that sort of made me feel bad...you typed out a whole paragraph of mine in just a few numbers and words, before I even finished writing my paragraph...

    It's hard for some while it comes so easily to others...but even if you find it hard, just think...probably all of the other people in your physics class can't grow CPs like you can

    Well I dont get grades for CPs because I didn't take botany :P, and also Anna A you taught me how to do it, along with Thez and drew...Your answers combined equalled one epic combo of learning. Atleast I learned one thing today. Thanks again!
