    Answer:0.71m/s^2

    Explanation:

    But we have to convert 1minute 25seconds to seconds.

    Since 60seconds=1minute 1minute 25seconds=85seconds

    Acceleration = (final velocity-initial velocity) : time

    Acceleration = (0-60) : 85

    Acceleration=-60/85

    Acceleration=-0.71m/s^2

    The minus sign indicate that the car is decelerating

    0.706 m/s/s because acceleration equals velocity over time
