\n" ); document.write( "----
\n" ); document.write( "Draw the picture.
\n" ); document.write( "You have a crossing point, a line segment going north
\n" ); document.write( "that is 35x miles long where \"x\" is time for Gregg and
\n" ); document.write( "for Peter, and a line segment going south that is 55x miles long.
\n" ); document.write( "----
\n" ); document.write( "Equation:
\n" ); document.write( "distance + distance = 225 miles
\n" ); document.write( "35x + 55x = 225
\n" ); document.write( "90x = 225
\n" ); document.write( "x = 2.5 hrs
\n" ); document.write( "----
\n" ); document.write( "Time when they are 225 miles apart: noon + 2.5 miles = 2:30 PM
