Algebra.Com's Answer #633718 by Boreal(15235) You can put this solution on YOUR website! The two together cover the entire state or 308 miles. \n" ); document.write( "bicycle speed=x mph \n" ); document.write( "car speed=x+36.8 mph \n" ); document.write( "bicycle traveled 5.5x miles in 5.5 hours \n" ); document.write( "car traveled 5.5x+36.8*5.5=5.5x+202.4 miles \n" ); document.write( "combined distance is 11x+202.4=308 miles \n" ); document.write( "11x=105.6 miles/hr \n" ); document.write( "x=9.6 mph BICYCLE \n" ); document.write( "x+36.8=46.4 mph CAR \n" ); document.write( "Together, the converge at 56 mph \n" ); document.write( "in 5.5 hours they cover 308 miles \n" ); document.write( " \n" ); document.write( " |
