    Please only post once. Thanks.

    Also please show some work and effort.

    One would have to elaborate, and also explain what is meant by 'reaction time'.

    In automotive operation, reaction time is the time that the driver sees something that initiates the braking action and the time that the brake is applied. That time period could be discerned with a period of constant or increasing velocity, with the assumption that decreasing velocity occurs when 1) the accelerator is released and 2) the brake is applied.
