Given data
[tex]\begin{gathered} 2\frac{3}{10}\text{ = }\frac{23}{10}\text{ miles before school} \\ \\ 1\frac{9}{10}\text{ = }\frac{19}{10}\text{ miles after school} \end{gathered}[/tex]
Next, equations for the total distance
[tex]\begin{gathered} \frac{19}{10}\text{ + }\frac{23}{10\text{ }}\text{ = }\frac{42}{10} \\ \\ Or \\ 1\frac{9}{10}\text{ + 2}\frac{3}{10}\text{ = 4}\frac{2}{10} \end{gathered}[/tex]
Final answer
[tex]\text{First and the last option are the correct answers.}[/tex]
