Answer for how to find average velocity and average acceleration based on graph

There's no information to describe the DIRECTION of the motion
at any time, so I'll have to work with speed instead of velocity.


Average speed = (total distance covered) / (time to cover the distance)

Distance covered in the first 8 seconds = 60 meters)
Distance covered in the middle 16 seconds = 240 meters
Distance covered in the last 21 seconds = 157.5 meters

Total distance covered = 457.5 meters
Time to cover the distance = 45 seconds

Average speed = (457.5 meters) / (45 seconds) = 10.17 m/s .


Average acceleration = (change in speed) / (time for the change)

Speed at the beginning = 0
Speed at the end = 0
Change in speed = 0
Time for the change = 45 seconds

Average acceleration = 0/45 = 0 .
