PHYSICS HELP

Hello everyone, I'm having difficulty answering this one problem, please if anyone can help I would greatly appreciate it:

The figure represents part of the performance data of a car owned by a proud physics student. (The horizontal axis is marked in increments of 2 s and the vertical axis is marked in increments of 2 m/s.)

(a) Calculate from the graph the total distance traveled.
<input ... > m

(b) What distance does the car travel between the times t = 2 s and t = 8 s?
<input ... > m

(c) Draw a graph of its acceleration versus time between t = 0 and t = 10 s.
(Do this on paper. Your instructor may ask you to turn in this work.)

(d) Write an equation for x as a function of time for each phase of the motion, as represented in the graph by 0a, ab, and bc. For part (i), choose an equation that provides the final position of the car at time tf in terms of the initial velocity and the acceleration. Use t within your equations as necessary to represent the quantity Δt (i.e. " tf - ti ").
