document.write( "Question 1070899: two cars leave towns 480 kilometers apart at the same time and travel toward each other. One car's rate is 20 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( "Is this correct?
\n" ); document.write( "3r+3(r-20)=480
\n" ); document.write( "3r+3r-60=480
\n" ); document.write( "6r-60=480
\n" ); document.write( "6r/6=540/6
\n" ); document.write( "r=90 ???? rate of the slower car? and is there a way to check this myself?

3x+3(x-20) = 480
\n" ); document.write( "3x+3x-60 = 480
\n" ); document.write( "6x = 540
\n" ); document.write( "x = 90
\n" ); document.write( "and the other:
\n" ); document.write( "x-20 = 90-20 = 70
\n" ); document.write( "-----------------------
\n" ); document.write( "check:
\n" ); document.write( "90+70 = 160
\n" ); document.write( "480/160 = 3 Correct
\n" ); document.write( "
\n" );
