The blue lake trail is 11 3/8 miles long. Gramma had home 2 1/2 miles each hour for 3 hours. How far is she from the end of the trail?

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
