    7.46 miles she has traveled from her house to the goal.

    Step-by-step explanation:

    total distance traveled = 1 3/4 + 2 1/3 + 3 3/8 miles

    =7/4 + 7/3 + 27/8 (converting the mixed numbers into improper functions)

    = 7 (6) + 7 (8) + 27 (3) / 24 (taking LCM)

    =42 + 56 + 81/24 (adding)

    = 179/24

    = 7.46 miles
