Inessa [10]

To find the miles for 3rd day, we take away the miles she biked for the first two day from the total.

$50 - 17 \dfrac{7}{8} - 18\dfrac{5}{7}$

$=50 - 17 \dfrac{7 \times 7}{8 \times 7} - 18\dfrac{5 \times 8}{7 \times 8}$

$= 48 \dfrac{112}{56} - 17 \dfrac{49}{56} - 18\dfrac{40}{56}$

$= 13 \dfrac{23}{56} \text { miles }$

Answer: She traveled 13 23/56 miles on the third day.
