    [SOLVED] Problem Solving Involving Fractions. Word Problems.

    Hi, I am new here and am struggling with a homework that will be due tomorrow. It is as follows. I will have a pic to help you guys out.


    W_____X_____Y.......Z

    X is 400 Km from Z. Y is 120Km from Z. W is moving from X towards Y and is _____ Km from Z. W has travelled 3/10 the distance from X to Y.

    At first it asks us (With different number) how for has W traveled from X to Y (In fraction). And they are switching the numbers that we have to figure out for each problem. So theres 3 more problems after this .

    We have:
    XZ=400 km and YZ=120 km.
    Then XY=XZ-YZ=400-120=280 km.
    Now, the distance that W traveled from X to Y is \displaystyle \frac{3}{10}\cdot 280=84 km.
