Distance = Rate x Time
\n" ); document.write( "Let x be the time spent at 88 mph and y the time at 154 mph.
\n" ); document.write( "1. $\"88x=154y\"$
\n" ); document.write( "2. $\"x%2By=8\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "From 1,
\n" ); document.write( " $\"x=%28154%2F88%29y\"$
\n" ); document.write( " $\"x=%287%2F4%29y\"$
\n" ); document.write( "Substituting,
\n" ); document.write( " $\"%287%2F4%29y%2By=8\"$
\n" ); document.write( " $\"%2811%2F4%29y=32%2F4\"$
\n" ); document.write( " $\"y=32%2F11\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"D=154%2832%2F11%29\"$
\n" ); document.write( " $\"D=448\"$ $\"miles\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
