    Step-by-step explanation:

    Answer

    Solution :-

    Let speed of train be x

    Let speed of car be y

    Now distance = Speed × Time

    Now,

    x

    320

    +

    y

    (600−320)

    =8+

    60

    40

    =8+

    __(1)

    x

    200

    +

    y

    (600−200)

    =8+

    60

    40

    +

    60

    30

    =8+

    3

    2

    +

    2

    1

    __ (2)

    solving (1) and (2)

    x=80y=60

    Speed of train = 80 km/hr

    speed of car = 60 km/hr
