A certain car is capable of accelerating at a rate of 0.60 m/s^2. How long does it take for this car to go from a speed of 55mi/h to a speed of 60 mi/h?

I know the answer is 3.7seconds! I am just confused on the steps to get the answer.

    Final velocity = Initial velocity - 9.8 * t

    Final velocity = 80.5 - 9.8 * 0.0124 = 80.378 m/s

    OR

    Final velocity = 80.5 - 9.8 * 16.416 = 80.378 m/s

    A. - 32 m/s

    B. - 97 m/s

    C. - 64 m/s

    D. - 81 m/s

    E. - 48 m/s
