    let d = distance from start
    then distance from finish = 2d

    total distance = 10 = d + 2d

    10 = d + 2d
    10 = 3d

    d = 10/3 = 3.333 km

    [soze=3]Hello, bigreddog![/soze]

    Jenna is twice as far from the finish line as she is from the start of a 10-km race.
    How far has she run?

    Did you make a sketch?
    Code:
          S            10 km            F
          | - - - - * - - - - - - - - - |
          :    x    :        2x         :
