    a)

    0.8 hours

    b)

    1.1 kilometers/min

    Step-by-step explanation:

    a)

    D = distance between town A and town B = 45 kilometers

    v = speed of the train traveling from town A to town B = 60 kilometers per hour

    t = time taken for the train to travel from town A to town B

    Time taken is given as

    t = D/v

    inserting the values

    t = 45/60

    t = 0.8 hours

    b)

    D = distance between town A and town B = 45 kilometers

    v = speed of the train traveling from town A to town B = ?

    t = time taken for the train to travel from town A to town B = 40 minutes

    Speed of the train is given as

    v = D/t

    inserting the values

    v = 45/40

    v = 1.1 kilometers/min
