\n" ); document.write( "in the opposite direction
\n" ); document.write( "After 4 hours the two cars are 420mi apart
\n" ); document.write( " 4x + 4(x + 5mph) = 420mi
\n" ); document.write( " 8x = 400
\n" ); document.write( " x = 50mph, speed of slower car, faster car's speed is 55mph
\n" ); document.write( "CHECKING our Answer***
