    Lets calculate how much she walks each weeks and then we multiply that by the number of weeks.

    weekWalk = 5 (2) + 3 = 10 + 3 = 13

    therefore, she walks 13 miles per week, if she walked for 29 weeks then we have:

    total walked = (29) (13) = 377

    so she walked 377 miles total, so her original estimate is not reasonable
