Answer:
Based on my calculations, she has 6 5/6 miles left.
Step-by-step explanation:
First, I converted all numbers to be the same fractions.
1 2/3 = 1 8/12
3/4 = 9/12
8 1/4 = 8 3/12
Then adding her current progress together equals 17/12 = 1 5/12
Finally, subtracting 1 5/12 from 8 3/12 equals 6 10/12
6 10/12 = 6 5/6
I don't know if the answer choices were a typo, but that is what I came to.
