    Answer:

    2.5 m/s²

    Explanation:

    Given,

    Initial speed ( u ) = 10 m/s

    Final speed ( v ) = 20 m/s

    Time ( t ) = 4 seconds

    To find : Acceleration ( a ) = ?

    Formula : –

    a = ( v – u ) / t

    a = ( 20 – 10 ) / 4

    = 10 / 4

    = 5 / 2

    a = 2.5 m/s²

    Therefore,

    The acceleration of the scooter is 2.5 m/s²
