    Answer:

    \sf Total \ Distance = 114\dfrac{4}{5} \ km

    Step-by-step explanation:

    Given;

    \sf \dashrightarrow \textsf{Distance covered by Amera} = \sf 32\dfrac{4}{5} \ km

    \sf \dashrightarrow \textsf{Part of the total distance that needs to be covered} \\\textsf{ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ in order to cover the full distance}  = \sf \dfrac{5}{7} \times Whole \ Distance

    Let the Whole distance be “D”, therefore;

    \sf \dashrightarrow \textsf{Part of the total distance that needs to be covered} \\\textsf{ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ in order to cover the full distance}  = \sf \dfrac{5}{7}D

    We know that;

    \dashrightarrow \textsf{ Distance covered} \ + \textsf{ Part of the total distance} \\\textsf{\ \ \ \ \ \ \ \ \ \ By Amera \ \ \ \ \ \ \ \ \ \ that needs to be covered to} \ \ \sf = Total \ Distance \\\textsf{\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ complete the whole distance}

    On substituting the values we get;

    \sf \dashrightarrow \ 32\dfrac{4}{5} \ + \ \dfrac{5D}{7} \ = \ D

    \sf \dashrightarrow \ 32\dfrac{4}{5} \ = \ D \ - \dfrac{5D}{7}

    On converting the mixed fractions to improper fractions we get;

    • [In-order to do so, we’ll multiply the denominator and the whole number, and add the product to the numerator]

    \sf \dashrightarrow \ \dfrac{(32 \times 5) + 4}{5} \ = \ D \ - \ \dfrac{5D}{7}

    \sf \dashrightarrow \ \dfrac{(160) + 4}{5} \ = \ D \ - \ \dfrac{5D}{7}

    \sf \dashrightarrow \ \dfrac{164}{5} \ = \ D \ - \ \dfrac{5D}{7}

    On taking LCM in the RHS we get;

    \sf \dashrightarrow \ \dfrac{164}{5} \ = \ \dfrac{7D - 5D}{7}

    \sf \dashrightarrow \ \dfrac{164}{5} \ = \ \dfrac{2D}{7}

    On transposing 7 to the LHS we get;

    \sf \dashrightarrow \ \dfrac{164 \times 7}{5} \ = \ \dfrac{2D}{1}

    \sf \dashrightarrow \ \dfrac{1148}{5} \ = \ \dfrac{2 \times D}{1}

    On transposing 2 to the LHS we get;

    \sf \dashrightarrow \ \dfrac{1148}{5 \times 2} \ = \ D

    On dividing 1148 and 2 we get;

    \sf \dashrightarrow \ \dfrac{574}{5} \ = \ D

    On converting the improper fraction to a mixed fraction we get; [Refer to the attachment]

    • To convert an improper fraction to a mixed fraction, divide the numerator by the denominator, the resulting quotient will be the whole number, the remainder will be the numerator, and the denominator will remain the same (original).

    ‎‎

    \sf \dashrightarrow D = 114\dfrac{4}{5} \ km.

    ‎‎

    Therefore, the total distance covered by Amera is 114 ⁴/₅ km.

    Let Amera has to cover x km distance

    Then, she still has to cover 5x/7 distance

    she covered (x- 5x/7)-2x/7 distance

    So,

    => 2x/7=164/5

    => x= 114.8 kms

    so, the total distance is 114.8 kms
