A bus makes a trip according to the position-time graph shown in the illustration. What is the average acceleration (in km/h²) of the bus for the entire 3.5-h period shown in the graph? +52.0 Position.x (km) ā= +39.0 +26.0 +13.0 + A 0 0.5 1.0 < Mi B 1.5 2.0 2.5 3.0 3.5 Time t(h)
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
I know that the velocities are constant in each segment. The time for a= 1hour, b=1.2, c=1.3

I'm getting that 8.17 is not correct for the practice problem, I do understand though that you have to divide the change in velocity by the change in time. Thank you for any feedback you have.
