Answer:
12 + (1/4 x 12) and 12 x 5/4
Explanation:
We're told that Elena walked 12 miles, she also walked 1/4 of the initial distance.
Let's go ahead and determine what 1/4 of 12 is;
[tex]\frac{1}{4}\text{ of }12=\frac{1}{4}\ast12=\frac{1}{1}\ast3=3[/tex]So the total distance Elena walked will be;
[tex]12+(\frac{1}{4}\ast12)=12+3=15miles[/tex]So our answers then will be 12 + (1/4 x 12) and 12 x 5/4
