Algebra.Com's Answer #333193 by chessace(471)![]() ![]() You can put this solution on YOUR website! 2nd car speed S MPH, then meet at time T (start of 2nd car). \n" ); document.write( "S*T = 50*(T+1) is the distance they each go. \n" ); document.write( "T(S-50)=50 \n" ); document.write( "T=50/(S-50) hours. \n" ); document.write( "Another way of looking at it is that the initial distance apart, 50m \n" ); document.write( "is decreasing by their relative speed (S-50): \n" ); document.write( "T=50/(S-50) hours. \n" ); document.write( " |
