Rachel is going on a 2 mile walk. She has already walked 1 3/4 miles. How much further does she have to go to finish her walk?

she has to go 1/4 miles more

Step-by-step explanation:

If she is going on a 2 mile walk and has already walked 1 3/4 miles you subtract that from 2 and get 1/4 of a mile left.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
