The distance between Exit 13 and Exit 14 is 0.9 mile farther than the distance between Exit 12 and Exit 13.

The distance between Exit 13 and Exit 15 is 6.8 miles farther than the distance between Exit 12 and Exit 14.

What is the distance between exit 14 and 15?

Answer 1

now you changed it

12 to 13 = 2.7
13 to 14 = 3.6

13 to 15 = 6.8 + 2.7 + 3.6 = 13.1

so
14 to 15 = 13.1 - 3.6 = 9.5
which is
13 to 15 - 13 to 14

Answer 2

Use a number line by the way
