Answer: [tex]3\dfrac{11}{20}\ \text{miles}[/tex]
Step-by-step explanation:
Given
Elisa run a total of [tex]8\frac{4}{5}[/tex] miles on Saturday and Sunday.
If she runs [tex]5\frac{1}{4}[/tex] miles on Saturday
Then, distance traveled on Sunday is given by
[tex]\Rightarrow 8\dfrac{4}{5}-5\dfrac{1}{4}\\\\\Rightarrow \dfrac{44}{5}-\dfrac{21}{4}\\\\\Rightarrow \dfrac{44\times 4}{5\times 4}-\dfrac{21\times 5}{4\times 5}\\\\\Rightarrow \dfrac{71}{20}\\\\\Rightarrow 3\dfrac{11}{20}\ \text{miles}[/tex]
