We add them up to find the total distance :
[tex] \dfrac{4}{10} + \dfrac{4}{10} = \dfrac{8}{10} = \dfrac{4 \times 2}{5 \times 2} = \dfrac{4}{5} [/tex]
[tex]\text {She walked } \dfrac{4}{5} \text { miles}[/tex]
[tex] \dfrac{4}{10} + \dfrac{4}{10} = \dfrac{8}{10} = \dfrac{4 \times 2}{5 \times 2} = \dfrac{4}{5} [/tex]
[tex]\text {She walked } \dfrac{4}{5} \text { miles}[/tex]
