    What are your ideas?
    Did you try to draw a graph of position vs time?

    Of course it can. You drive 50 miles and it takes you an hour, so your average speed is 50 miles/hour. But nothing about that stops you from driving 100 mph for the first mile, and then slowing down. (Or any number of variations, as long as it takes you an hour to complete the trip.
