Lynn walked for 2 hours and then ran for 30 minutes.
\n" ); document.write( "If she ran twice as fast as she walked and she covered 12 miles altogether,
\n" ); document.write( "then how fast did she walk?
\n" ); document.write( "-------
\n" ); document.write( "Walking DATA:
\n" ); document.write( "time = 2 hrs; rate = x mph ; distance = 2x miles
\n" ); document.write( "-------------------------------
\n" ); document.write( "Running DATA
\n" ); document.write( "time = 1/2 hr ; rate = 2x mph ; distance = (1/2)(2x) = x miles
\n" ); document.write( "-------------------------------
\n" ); document.write( "Equation:
\n" ); document.write( "distance + distance = 12 miles
\n" ); document.write( "2x + x = 12
\n" ); document.write( "3x = 12
\n" ); document.write( "x = 4 miles (distance she ran)
\n" ); document.write( "----
\n" ); document.write( "Walking rate = x = 4 mph
\n" ); document.write( "================================
