You can put this solution on YOUR website!
18 seconds * (1 min/60 seconds)*(1 hr/60 min) = 0.005 hours\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "264 feet * (1 mile/5280 feet) = 0.05 miles\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-------------------------------------------------------\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "d = rt\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "0.05 = r*0.005\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "0.05/0.005 = r\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "10 = r\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "r = 10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the runner's speed is 10 miles per hour.\r
