Mike said, last week I ran 15 miles farther than Bill. Pete said Last week I ran one mile less than 3 times as far as Bill. If Mike and Pete ran the same distance, how far did Bill run?

Bill -- x
mike --- x+15
Pete --- 3x - 1

3x-1 = x+15
2x = 16
x = 8

bill ran 8 miles

check:
Bill -- 8 miles
Mike -- 23 mi
Pet -- 23 mi
Yeah!
