Solution

The correct option is A 11 miles
$A v e r a g e = \frac{S u m o f a l l d a t a p o i n t s}{N u m b e r o f d a t a p o i n t s}$

Average distance covered by Alex
$= \frac{S u m o f t h e d i s t a n c e s}{N u m b e r o f d a y s}$

That is,
$A v e r a g e = \frac{6 + 10 + 8 + 10 + 13 + 15 + 15}{7}$
$= \frac{77}{7} = 11 m i l e s$

Thus, the average distance Alex covers each day is 11 miles.
