    So 8th week:20

    13th week:33

    13-8=5

    33-20=13

    grouth of 13 per 5 weeks or about 2.6 increse per week

    so if she ran 37 miles then

    37-33=4

    so an increse of 4 or about 1.5 more weeks soweek 14.5

    another way is to find the ratio of miles to weeks

    20/8=2.5

    33/13=2.54

    average 2.5 and 2.54 and get 2.52

    37/x=2.52

    solve for x

    37/x=2.52

    multiply both sides by x

    37=2.52x

    divide both sides by 2.52

    14.68=x

    she is on her 14.68 week
