Suppose an arrow is shot upward on the moon with a velocity of 48 m/s, then its height in meters after t seconds is given by h(t) = 48t - 0.83t". Find the average velocity over the given time intervals.

Then, use the trend/pattern you see to estimate the slope of the tangent line. Your answer should be accurate to at least 2 decimal places.
