Convert $\"+5+\"$ sec to hours
\n" ); document.write( " $\"+5+\"$ sec x $\"+1%2F60+\"$ min/sec x $\"+1%2F60+\"$ hrs/min =
\n" ); document.write( " $\"+5+%2F+3600+\"$ hrs
\n" ); document.write( "----------------------
\n" ); document.write( "Use $\"+d+=+r%2At+\"$ with units of miles and hours
\n" ); document.write( " $\"+d+=+540%2A%28+5%2F3600+%29+\"$
\n" ); document.write( " $\"+d+=+.75+\"$ mi
\n" ); document.write( "Convert to feet
\n" ); document.write( " $\"+.75+\"$ mi x $\"+5280%2F1+\"$ ft/mi = $\"+3960+\"$ ft
\n" ); document.write( "The plane travels 3,960 ft in 5 sec\r
\n" ); document.write( "
