Given:

Total distance =
6(1)/(5) miles

Hiking before lunch =
2(2)/(3) miles

To find:

How much further does Sylvia have left to hike?

Solution:

Let x be the remaining hiking distance.

We know that,

Total hiking distance = Hiking before lunch + Remaining hiking distance


6(1)/(5)=2(2)/(3)+x


((6* 5)+1)/(5)=((2* 3)+2)/(3)+x


(30+1)/(5)=(6+2)/(3)+x


(31)/(5)=(8)/(3)+x

Isolate variable term.


(31)/(5)-(8)/(3)=x


(93-40)/(15)=x


(53)/(15)=x

It can be written as


(45+8)/(15)=x


((3* 15)+8)/(15)=x


3(8)/(15)=x

So,
3(8)/(15) miles left to hike.

Therefore, the correct option is C.
