Two bicycle riders start at the same point and travel in opposite directions. One travels 5 kilometers per hour faster than the other. In 3 hours they are 117 kilometers apart: How fast is each traveling?
\n" ); document.write( "--------
\n" ); document.write( "1st rider DATA:
\n" ); document.write( "time = 3 hrs. ; rate = x km/h ; distance = 3x km
\n" ); document.write( "------------------------
\n" ); document.write( "2nd rider DATA:
\n" ); document.write( "time = 3 hrs. ; rate = x+5 km/h ; distance 3(x+5) km
\n" ); document.write( "==========================
\n" ); document.write( "Equation:
\n" ); document.write( "distance + distance = 117 km
\n" ); document.write( "3x + 3(x+5) = 117 km
\n" ); document.write( "3x + 3x+15 = 117
\n" ); document.write( "6x = 102
\n" ); document.write( "x = 17 km/h (1st rider rate)
\n" ); document.write( "====
\n" ); document.write( "x+5 = 22 km/h (2nd rider rate)
\n" ); document.write( "=================================
