$2.05\ miles$ or $2\frac{1}{20}\ miles$

Step-by-step explanation:

we know that

To calculate the total distance Barb walked, add the distance to her friend's house plus the distance to the library.

$1.3+\frac{3}{4}$

Remember that

$1.3=\frac{13}{10}$

substitute

$\frac{13}{10}+\frac{3}{4}=\frac{13*2+5*3}{20}$

$=\frac{41}{20}\ miles$

$=2.05\ miles$

Convert to mixed number

$\frac{41}{20}=\frac{40}{20}+\frac{1}{20}=2\frac{1}{20}\ miles$
