    The average speed is 8.0 km/h

    Explanation:

    We use the data for the return journey to calculate the distance travelled using the constant velocity equation:

    s=vt=6⋅4=24 km

    Note I didn't change any units so the answer comes out in kilometres.

    Now use the distance and time taken to travel to Guam to find the average speed:

    v = st = 243 = 8.0 km/h
