    Answer:

    9.09m/s

    Explanation:

    Speed = Distance/Time

    Distance = 495km

    Time = 4 hr 30 min = 4 hr 1/2hr = 4.5 hr

    Therefore, Speed = 495/4.5 = 110km/h

    Now to convert km/h to m/s

    110 x 1000/ 110 x 110

    110 cancels out each other, we are now left with

    1000/110 = 9.09m/s
