Answer:

12 km

Step-by-step explanation:

m = b + 8

p = 3b - 1

p = m + 15

p = m + 15....and m = b + 8....so we  are gonna sub

p = b + 8 + 15

p = b + 23

b + 23 = 3b - 1

23 + 1 = 3b - b

24 = 2b

24/2 = b

b = 12 <==== Bill ran 12 km

m = b + 8

m = 12 + 8

m = 20 km....this is what mike ran

p = m + 15

p = 20 + 15

p = 35 km....this is what pete ran
