Answer 2

Answer:

$3\frac{1}{10}$ miles

Step-by-step explanation:

The total distance of Charles bike ride is  = $8\frac{1}{2}$ miles

He has covered the distance = $5\frac{2}{5}$ miles

We will subtract his covered distance from total distance.

He still have to go = $8\frac{1}{2}$ - $5\frac{2}{5}$

                              = $\frac{17}{2}$ - $\frac{27}{5}$

                              = $\frac{85-54}{10}$

                              = $\frac{31}{10}$

                              = $3\frac{1}{10}$ miles

He still have to go $3\frac{1}{10}$ miles
