    Answer:

    8mph

    Step-by-step explanation:

    Let call X is trip there speed

                    R  x   t  = D

    # to           X      3 = 3X

    # Return   6      4 = 24

    Because the distance when we go to and back are the same, so we have:

    3X = 24

    <=> X = 8

    So the avergage speed of the trip there is 8mph
