    Assume that the distance from New York to Miami is d and that half the distance is traveled at 45mph and half the distance is traveled at 55mph.

    If the average velocity is given by
    d/T=d/[0.5d/45+0.5d/55]

    I'm drawing a complete disconnect between the line above and this:

    =99/2=49.5(mph)

    I'm canceling the d from num and the denom to get
    d/T=1/[0.5/45 + 0.5/55]
    then
    d/T=[45/0.5 + 55/0.5]=100/.5=200 (which I know is not the answer!).

    What am I doing wrong?
