Question 7660: In Baseball the pitcher's mound is 60.5 feet from home plate. The strike zone , or distance across the plate, is 17 inches. If a pitcher throws a baseball 90 miles per hour, how many seconds does it take for the baseball to reach home plate? How long is the ball in the strike zone?

First, convert 90 mph to feet per second (fps).
%2890+mph%29%2A%285280+ft%2Fmi%29%2F%283600+secs%2Fhr%29=+132+fps
The baseball travels at 132 fps. How long does it take to travel 60.5 ft.?
%2860.5ft%29%2F132fps+=+0.4583secs to reach home plate.
Now convert 132 fps into inches per second (ips).
%28132fps%29%2A%2812inches%2Fft%29+=+%281584ips%29
At a speed of 1584 ips, how long does it take the baseball to travel 17 inches?
%2817inches%29%2F%281584+ips%29+=+0.0107secs to cross the strike zone.
