    1. The problem statement, all variables and given/known data
    A car moving at constant acceleration covers the distance between two points 58m apart in 6.2 seconds. its speed as it passes the second point is 54 km/hr. what is the speed at the first point? at what prior distance from the first point was the car at rest?

    2. Relevant equations
    58m/6.2s =9.36m/s 9.36 m/s converts to .5616km/hr. 54 km/hr * .5616km/hr = 30.33 km/hr

    3. The attempt at a solution
    The speed at the first point is 30.33 KM/Hr. Not sure how to arrive at the second part.

    What kinematic equations are you using?

    And what have you been given in the question?
