A ball is thrown upward from the top of a building. The function below shows the height of the ball in relation to sea level, f(t), in feet, at different times (t) in seconds:

f(t) = -16t2 + 48t + 100

The average rate of change of f(x) from x = 3 seconds to x = 5 seconds is _____feet per second. (4 points)
