A pitcher can throw a baseball 95 miles per hour. The ball travels at that speed for 56 feet, until it arrives at the batter. How many seconds, correct to the nearest thousandth of a second, does the batter have from the moment the ball is thrown, until it arrives.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The easiect way is to 1st convert 56 feet to miles. Since 5,280 feet = 1 mile, then 56 feet = $\"56%2F5280\"$ = 0.010606061 mile\r
\n" ); document.write( "\n" ); document.write( "We now use the formula, D = RT, or $\"T+=+D%2FR\"$ to find the time, in hours\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore, Time, or T, in hours = $\"0.010606061%2F95\"$ = 0.000111643 hour\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since 3,600 seconds = 1 hour, we now convert 0.000111643 to seconds by multiplying it by 3,600.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This gives us 0.000111643 * 3600 = 0.401913876, or $\"highlight_green%280.402%29\"$ of a second. \n" ); document.write( "

\n" );
