The answer is:
C and D
Explanation;
Janie walked 10 miles first.
Then they walked 15 times the original 10 miles.
When you place that in a calculation, it looks like this:
10miles + (15 x 10miles)
Which is basically 10 + 15 x 10.
= 160
With D, you just use multiplication.
10 x 1 = 10
10 x 15 = 150
= 160
