Answer:
Gramma is 3 7/8 miles away from the end.
Step-by-step explanation:
To find this, we first need to know how far Gramma has walked. We can find this by multiplying her rate by the amount of time.
2 1/2 * 3 = 7 1/2
Now we subtract how far she has walked by the length of the trail.
11 3/8 - 7 1/2 = 3 7/8
