Using a telescope, you track a rocket that was launched 15 km away recording the angle 0 between the telescope and the ground at half-second intervals. Estimate the velocity of the rocket if 0(10) = 0.205 and 0(10.5) = 0.225. (Give your answer in kilometers (km) per hour (h) and round to one decimal place.)
