Question

Liz is hiking a trail that is 0.8 miles long. Liz hikes the first 2 tenths of the distance by herself. She hikes the rest of the way with her friends. How far does Liz hike by herself ?

Answer 1

i think that it is 0.16 because 0.8 x 0.2 = 0.16

Answer 2

Liz hiked 0.16 miles by herself.

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* (1)/(10)=(2)/(10)`th of the total distance.

So, the distance that she covered by herself is,

`=\text{Total distance}* \text{The portion she covered}`

`=0.8* (2)/(10)`

`=0.16` miles

Therefore, Liz hiked 0.16 miles by herself.
