To find the total distance Elena walked we have to divide it into two parts:

"Elena walked 12 miles"

"And walked 1/4 of this distance"

Mathematically this means:

[tex]12+(\frac{1}{4}\times12)[/tex]

1/4 of 12 miles is 3 miles! So the total distance is 12 + 3 = 15 . Let's see the alternatives:

A) Do not apply (total not 15 miles).

B) Do not apply (total not 15 miles).

C) Correct!

D) Correct (not that if you put 12 in evidence the expression is the same as it is on C).

E) Do not apply (total not 15 miles).

F) Correct! (total is 15 miles --> 12x5 = 60/4 = 15).
