You can put this solution on YOUR website!
You need to convert: 500ft per 75 secs into miles per hour.
\n" ); document.write( "To convert ft/sec into mph, you would divide the number of feet by 5,280 feet/mile, and to convert seconds to hours, you would divide the number of seconds by 3,600 secs/hour.
\n" ); document.write( "Let's see how this works:
\n" ); document.write( "(500 ft)/(75 secs) = (500 ft/5280 ft per mile)over(75 secs/3600 secs per hour)= 4.54 miles per hour. \n" ); document.write( "

\n" );
