How do I put the following question into an expression with a variable?
\n" ); document.write( "A police helicopter clocked an automobile for 10 seconds over a stretch of highway on fifth of a mile long.
\n" ); document.write( "--------------------------------------------------------
\n" ); document.write( "At what rate was the automobile traveling in miles per
\n" ); document.write( "A. Second?
\n" ); document.write( "[1/5] mile / [10]sec = [1/50](mile/sec)\r
\n" ); document.write( "\n" ); document.write( "--------------------------------------------------------
\n" ); document.write( "B. Hour?
\n" ); document.write( "{[1/5] mile / [10]sec } = {[1/50](mile/sec)}*{3600 sec/1 hr}
\n" ); document.write( "= 72 miles/hr.
\n" ); document.write( "============================
