If the bike and the car met after 8.5 hours and the car traveled 30.8 MPH faster than the bike, find the average rate of each \n" ); document.write( "
Algebra.Com's Answer #616069 by mananth(16946)![]() ![]() You can put this solution on YOUR website! Let cyclist speed be x mph \n" ); document.write( "car speed = (x+38.5) mph\r \n" ); document.write( "\n" ); document.write( "both of them take the same time to meet = 8.5 hours\r \n" ); document.write( "\n" ); document.write( "Distance = 442 miles\r \n" ); document.write( "\n" ); document.write( "Combined speed = 2x+38.5\r \n" ); document.write( "\n" ); document.write( "t= d/r\r \n" ); document.write( "\n" ); document.write( "8.5 = 442/(2x+38.5)\r \n" ); document.write( "\n" ); document.write( "8.5(2x+38.5) =442\r \n" ); document.write( "\n" ); document.write( "17x + 327.5 = 442\r \n" ); document.write( "\n" ); document.write( "17x= 442-327.5\r \n" ); document.write( "\n" ); document.write( "17x = 114.5\r \n" ); document.write( "\n" ); document.write( "x=6.75 mph...cycle speed\r \n" ); document.write( "\n" ); document.write( "add 38.5 to get car speed\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
