One car'srate is 14 kilometers per hour less than the other's. If they meet in 3 hours, what is the rate of the slower car? \n" ); document.write( ".. \n" ); document.write( "let x=rate of slower car \n" ); document.write( "x+14=rate of faster car \n" ); document.write( "Both cars are traveling toward each other at a rate=x+(14+x)=2x+14 \n" ); document.write( "travel time*rate=distance \n" ); document.write( "3(2x+14)=480 \n" ); document.write( "6x+42=480 \n" ); document.write( "6x=452 \n" ); document.write( "x=73 \n" ); document.write( "what is the rate of the slower car? 73 km/hr \n" ); document.write( " |
