    Answer: 71.5minutes

    Step-by-step explanation:

    Andres

    Distance 5km

    Time= 13minutes

    Andrea’s sister race covered = 11/2 of Andres’s distance

    11/2*5=27.5km

    5km=13minutes

    27.5km=xminutes

    5x=13*27.5

    5x= 357.5

    X=357.5/5

    X=71.5minutes

    It will take Andres’s sister 71.5minutes to complete her race
