Explanation:

Step1: Identify initial distance

Initial distance: $1\frac{7}{10}$ miles

Step2: Convert to improper fraction

$1\frac{7}{10} = \frac{1\times10 + 7}{10} = \frac{17}{10}$ miles

New distance to add: $\frac{2}{10}$ miles
Total distance: $\frac{17}{10} + \frac{2}{10} = \frac{19}{10}$ miles
