Car I speed= 45 mph , starts at
\n" ); document.write( "Car II speed= 60 mph starts at
\n" ); document.write( "
\n" ); document.write( "Time difference between the starting of the two= 2.00 hours
\n" ); document.write( "
\n" ); document.write( "Time taken by Car I = X / 45
\n" ); document.write( "Time taken by Car II = X / 60
\n" ); document.write( "
\n" ); document.write( "X / 45 - X / 60 = 2
\n" ); document.write( "
\n" ); document.write( "LCD - 90
\n" ); document.write( "Multiply equation by 90 90
\n" ); document.write( "
\n" ); document.write( "2 x - 1.5 x = 180
\n" ); document.write( "0.5 x = 180
\n" ); document.write( "/ 0.5
\n" ); document.write( "x= 360 miles
\n" ); document.write( "Car II speed= 60 mph
\n" ); document.write( "Distance = 360 miles
\n" ); document.write( "Time taken = 360 / 60
\n" ); document.write( "Time taken = 6 hour
\n" ); document.write( " \n" ); document.write( "

\n" );
