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?

  • algebra - ,

    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!
