Question

Mr. George is walking while wearing a 50-pound backpack. He walked 3 1/4 miles before taking a break. He then walked an additional 2 2/5 miles. How many miles did he walk in all?

Answer 1

Answer: $5 \dfrac{13}{20}\ \text{miles}$

Step-by-step explanation:

Given

George walks $3 \frac{1}{4}$ before taking break

then he walks additional $2 \frac{2}{5}$ miles

total distance walked

$\Rightarrow 3 \frac{1}{4}+2 \frac{2}{5}=\frac{12+1}{4}+\frac{10+2}{5}\\\Rightarrow \frac{13}{4}+\frac{12}{5}=\frac{13\times 5+12\times 4}{20}\\\Rightarrow \frac{113}{20}=5 \frac{13}{20}\ \text{miles}$
