Question

Joey starts riding his scooter from his apartment to campus. He thinks it would be fun to make a graph of
his position relative to time. By a weird coincidence, the graph is perfectly modeled by the equation

3t^2 -5t + 6 

He tells his friend Andie that his average velocity for the second half of his trip was 39.2 units per time
interval, because the slope formula says to do

(256 - 60)/(5 -10)

Is Joey correct?
