s = d / t
\n" ); document.write( "---
\n" ); document.write( "s + w = 300/1.5
\n" ); document.write( "s + w = 200
\n" ); document.write( "---
\n" ); document.write( "s - w = 300/3
\n" ); document.write( "s - w = 100
\n" ); document.write( "s = 100 + w
\n" ); document.write( "---
\n" ); document.write( "s + w = 200
\n" ); document.write( "100 + w + w = 200
\n" ); document.write( "2w = 100
\n" ); document.write( "---
\n" ); document.write( "w = 50 mph
\n" ); document.write( "s = 150 mph
