Answer:

19/20 of a mile.

Step-by-step explanation:

\frac{3}{10} + \frac{1}{4} + \frac{2}{5}

The common denominator is 20 so we times the first one by 2 the second one by 5 and the last one by 4. (Both numerator and denominator.)

You will end up with this \frac{6}{20} + \frac{5}{20} + \frac{8}{20} = \frac{19}{20}
