First, finding a time it takes to get the baseball to homeplate: t = S / V, where S is the distance traveled and V is the velocity. t = 60 ft / 85 mi/h = [1 Mile = 5280 Feet] = 60 / (85 * 5280) =0.00013369 h = 0.0080214 min. Second, calculating the number of revolutions made: N = t * n = 0.0080214 * 1800 = 14.43852 = approx. 14.5 revolutions. Answer: 14.5 revolutions.
