    Lines that look parallel in the picture are parallel. Express "b". the length of the middle line segment as a common fraction.

    i think its (1+2)*(2/5)=1.2

    1+2 are sum of the lengths, since its 2/5 down (2+3=5), i multiplied by 2/5

    I'm assuming the line with 2 and 3 is perpendicular to the lines with 1 and 2

    It doesn't show in the diagram though.

    But, i believe it is right since the median equals to one-half of the sum, and the median divides the two parts in half. For this problem, "b" is 2/5.
