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

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
