    97.5 km/h

    Explanation:

    The time taken by gino = 6 hours

    Speed of Gino = 65 km/h

    The expression for distance is : -

    Distance = Speed x Time

    So, The distance covered by Gino = 65 km/h x 6 hrs = 390 km

    The same distance is covered by Lorry.

    Time taken by Lorry is 2 hrs fewer than Gino = 4 hours

    Speed = Distance/Time = 390 km/4 h = 97.5 km/h

    97.5 km/h is the average speed of Lorry for the whole journey.
