Answer:
Liz hiked 0.16 miles by herself.
Step-by-step explanation:
Liz is hiking a trail that is 0.8 miles long. So the total length of her hiking is 0.8 miles.
Liz hiked the first 2 tenths of the distance by herself i.e she hiked \(2\times \dfrac{1}{10}=\dfrac{2}{10}\)th of the total distance.
So, the distance that she covered by herself is,
\(=\text{Total distance}\times \text{The portion she covered}\)
\(=0.8\times \dfrac{2}{10}\)
\(=0.16\) miles
Therefore, Liz hiked 0.16 miles by herself.
