\n" ); document.write( "----
\n" ); document.write( "You DATA:
\n" ); document.write( "rate = 18 mph ; time = t hrs ; distance = r*t = 18t miles
\n" ); document.write( "-----
\n" ); document.write( "Friend DATA:
\n" ); document.write( "rate = 12 mph ; time = t hrs ; distance = 12t miles
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "your distance - 3 miles = friend's distance
\n" ); document.write( "18t - 3 = 12t
\n" ); document.write( "----
\n" ); document.write( "6t = 3
\n" ); document.write( "time = 1/2 hour (time for you to catch up with your friend)
