To find how long it takes for the ball to reach the point above home plate
\n" ); document.write( "you would divide distant by speed,
\n" ); document.write( "which is the same as multiplying distance times the reciprocal of speed:
\n" ); document.write( "\"speed=distance%2Ftime\" <--> \"time=distance%2Fspeed\" <--> \"time=distance%281%2Fspeed%29\"
\n" ); document.write( "
\n" ); document.write( "We just have to deal with unit conversions.
\n" ); document.write( "One mile is \"5280\" feet,
\n" ); document.write( "so \"1mile%2F%225280+feet%22\" and \"5280+feet%2F%221+mile%22\"
\n" ); document.write( "are our \"reduction-of-unit-multipliers\" for distance.
\n" ); document.write( "One hour is 60 minutes and \"3600\" seconds,
\n" ); document.write( "so \"1+hour%2F%223600+seconds%22\" and \"3600+seconds%2F%221+hour%22\"
\n" ); document.write( "are our \"reduction-of-unit-multipliers\" for time.
\n" ); document.write( "Beyond that, I hope we do not need to 80/
\n" ); document.write( "60 feet 6 inches = 60.5 feet.
\n" ); document.write( "
\n" ); document.write( "The speed of the ball in feet per second is
\n" ); document.write( "\"%28100miles%2F%221+hour%22%29%281+hour%2F%223600+seconds%22%29%285280+feet%2F%221+mile%22%29\"\"%22=%22\"\"5280feet%2F%2236+seconds%22\"\"%22=%22\"\"%22about+146.7+feet+%2F+second%22\"
\n" ); document.write( "
\n" ); document.write( "The time for the ball to reach just above home plate is
\n" ); document.write( "\"60.5feet%2836seconds%2F%225280+feet%22%29=0.4125seconds\"
\n" ); document.write( "
\n" ); document.write( "Maybe that is the expected answer.
\n" ); document.write( "It seems to be a very short time to decide how to move and get the bat to the right position to meet the ball.
