The height in feet, h, of a model rocket t seconds after launch is given by the equation h(t)=3+70t-16t^2 The average rate of change in h(t) between t = 1 second and t = 3 second is 6. What does the average rate of change tell you about the rocket?

The rocket is traveling six times as fast when t = 3 than it is when t = 1.
The rocket is at a greater height when t = 3 than it is when t = 1.

The rocket is 6 feet higher above the ground when t = 3 than it is when t = 1.

The rocket is traveling at a constant rate of 6 feet per second between t = 1 and t = 3.
