two motorcyclists started at the same point and travel in opposite directions. one travels 6 mph faster than the other.In 4 hours they are 432miles apart. how fast is each traveling?






speed of slower mph

speed of faster mph

  • algebra -

    let speed of slower be x mph
    then speed of the faster is x+6 mph

    distance covered by slower = 4x
    distance covered by faster = 4(x+6)
    4x + 4(x+6) = 432
    8x + 24=432
    8x = 408
    x = 51

    the slower went 51 mph, the faster went 57 mph
