Peter and Sophia launch two model rockets from different initial heights. The height, h(t), in feet, of Peter's rocket t seconds after launch is modeled by the equation h(t)= - 16+2 +64t + 80, where -16 represents the gravity constant in feet per second squared and 64 represents the
initial velocity in feet per second.
Sophia launches her rocket from an initial height that is half the height from where Peter's rocket is launched. The initial velocity of Sophia's
rocket is twice the initial velocity of Peter's rocket.
What is the difference, in feet, between the maximum height of Peter's rocket and the maximum height of Sophia's rocket?
