Answer:
Distance Maria had to walk in the afternoon is [tex]2\frac{7}{8}[/tex]
Step-by-step explanation:
Lets take that Maria walked [tex]x[/tex] miles in the afternoon.
Distance walked in the morning + distance walked in the afternoon = [tex]10\frac{1}{8}[/tex]
⇒[tex]7\frac{2}{8} +x=10\frac{1}{8}[/tex]
[tex]\frac{58}{8} +\frac{8x}{8} =\frac{81}{8}[/tex]
[tex]\frac{58+8x}{8} =\frac{81}{8}[/tex]
[tex]58+8x=81[/tex]
[tex]8x=81-58\\[/tex]
[tex]8x=23[/tex]
[tex]x=\frac{23}{8}[/tex]
[tex]x=2\frac{7}{8}[/tex]
