Simple, just add the values of the school distance with the library distance, then substract the distance to the park.

If you are lazy like me, the answer is C, 1.08.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
