In baseball the pitcher's mound is 60.5 feet from home plate. The strike zone, or distance across the plate, is 17 inches. The time it takes for a baseball to reach home plate can be determined by dividing the distance the ball travels by the speed at which the pitcher throws the baseball. If a pitcher throws a baseball at 90 miles per hour, how many seconds does it take for the baseball to reach home plate?
