    Answer:The integral of acceleration = velocity

    Step 1. write a linear equation for the graph ... a = some function of t - -

    (hint - - from alg 1, use y = mx + b)

    Step 2. - - - integrate to get a velocity equation. use the initial condition to find C ... (At t = 0, the velocity of the car is 0)

    -- - the integral of velocity = displacement (or position)

    step 3. integrate the velocity equation from step 2 to get a position vs time equation

    -- - use the initial condition to find C (At t = 0, its position is 10)

    step 4. answer the question
