    Answer:

    57 million kilometres

    Explanation:

    We are given that:

    1 light year = 9.5 million kilometres

    To get 6 light years, we simply multiply 6 by 9.5 million kilometres:

    6 light years = 6 * 9.5 million= 57 million kilometres

    St Bernard’s star is 57 million kilometres away from the earth.
