    Driving along a steady speed of 26m/s and suddenly see a child 150m from you. Breaks can produce acceleration of -2.5m/s^2 but it takes time to get the foot from the gas to the brake pedal. How much time do you have, if to avoid hitting the child?

    What distance to come to a stop?
    How much of the 150 m is left?
    How long to travel that distance?

    I guess it is how long to travel the distance. I copied the exact question I got.
