Penny run a distance of 1.6 miles.

Step-by-step explanation:

Penny first ran 1/10 of a mile four times. Distance coves by her is :

$d_1=\dfrac{1}{10}\times 4=0.4\ miles$

Penny ran next 1/5 of a mile three times. Distance,

$d_2=\dfrac{1}{5}\times 3=0.6\ miles$

Penny finally ran 3/10 of a mile two times. Distance,

$d_3=\dfrac{3}{10}\times 2=0.6\ miles$

Total distance covered by Penny :

$d=d_1+d_2+d_3\\\\d=0.4+0.6+0.6\\\\d=1.6\ miles$
