Answer: [tex]5 \dfrac{13}{20}\ \text{miles}[/tex]
Step-by-step explanation:
Given
George walks [tex]3 \frac{1}{4}[/tex] before taking break
then he walks additional [tex]2 \frac{2}{5}[/tex] miles
total distance walked
[tex]\Rightarrow 3 \frac{1}{4}+2 \frac{2}{5}=\frac{12+1}{4}+\frac{10+2}{5}\\\Rightarrow \frac{13}{4}+\frac{12}{5}=\frac{13\times 5+12\times 4}{20}\\\Rightarrow \frac{113}{20}=5 \frac{13}{20}\ \text{miles}[/tex]
