    Answer: the average speed was 8.0km/h

    Explanation: We use the data for the return journey to calculate the distance travelled using the constant velocity equation:
    s = vt = 6 x 4 = 24km

    Note I didn’t change any units so the answer comes out in kilometers.

    Now use the distance and time taken to travel to Guam to find the average speed:
    v = s/t = 24/3 = 8.0km/h
