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