You can put this solution on YOUR website! Hi dear!
Let m=mike
P=pete
B=bill
From the first sentence,if mike ran 8km more than Bill then,
m=8+B------(1)
if pete ran 1km less than three times as Bill,then,
P=3B-1------(2)
From your last sentence,
pete ran 15km further than mike,then,
P=15+M-----(3)
now,
From equ (3),
M=P-15-----(4)
put equ (4) in (1)
P-15=8+B
P=8+15+B
P=23+B-----(5)
Put equ (5) in (2)
23+B=3B-1
collect like terms
3B-B=23+1
2B=24
divide both sides by 2
B=12
Bill ran 12km
HOPE THIS HELPS;
