    Answer:

    80 km/h

    Step-by-step explanation:

    we know that,Speed = Distance/Time

    Two third of 540 km = 540* 2/3= 360 km

    So, 60 km/h = 360 km/ t hour

    => t hour = 6 hour

    For the one third journey train took (8hr15min-6hr)= 2hr15min and the one third journey is 180 km

    15 min can be written as 1/4 hour

    So,the speed for the rest of the journey

    = 180km/(2+1/4) hour

    = 180 km/ (9/4) hour

    = 180*4/9 km/h

    = 20*4 km/h

    = 80 km/h
